Over the summer of 2015, I worked at one of NYU’s neuroscience laboratories. From early July to mid August, I studied neuroscience from a textbook and many research articles that broadened my knowledge on the human brain and the human nervous system. I was loaned a neuroscience textbook called “Neuroscience: Exploring the Brain”. I used this textbook as my primary source of information. When my junior year of high school ended in June, I thought I would spend my summer learning about the lymphatic system, as it had intrigued before, but I had never really delved into the topic. Once I began working in the lab, I adopted a greater appreciation for the nervous system. As I learned more and more about the nervous system, I realized how fragile …show more content…
Afferent nerves bring messages from external stimulus (sensations i.e.: touch, temperature, pain) through the peripheral nervous system, and into the central nervous system. Efferent nerves send impulses from the brain and central nervous system to the peripheral nervous system. This causes us to move, digest, or any other number of conscious/unconscious actions. The somatic nervous system is a branch of the peripheral nervous system that is in charge of voluntary control of body movements such as walking or raising a hand. The autonomic nervous system is the other branch of the peripheral nervous system, and is in charge of non-voluntary bodily functions such as digestions, heart rate, etc. The autonomic nervous system is also in control of all fight or flight reactions, as they are not reactions that are consciously thought out, but rather happen out of our conscious …show more content…
Once it was cut out, I began to sketch where the nerves and central nervous system would be painted on later. Because the spine is divided into many different sections (starting from the neck down: cervical, thoracic, lumbar, sacrum and coccyx) I labeled and drew out where the spinal nerves would emerge. I used a reference photo1 to see where the spinal nerves spread out in the body. I cut out the head template, and cut a strip out from where the central nervous system would be on the body. I bought LED light strips to place in the cutout strip to indicate where the central nervous system resides and to imply its importance. Once I had drawn out the placement of the nerves, I began hand painting the individual branches, starting with the cervical area and working my way down to the coccyx. This painting stage took me several days, as each section brought a new shape and width to each nerve. I used white paint for the nerves because I thought the contrast would be aesthetically pleasing while remaining sophisticated and clear. This also meant that any errors in my painting would be very clear, so I needed to be very
The protocol and conceptual overview of these procedures can be found under the header, “Properties of Skeletal Muscle” in NPB 101L Physiology Lab Manual Second Edition (Bautista & Korber, 2009, 9-17). The test subject for this lab was the Northern Leopard frog whose spinal cord and brain were severed. In order to carry out the experiments, the materials needed were one medium length surgical scissor, two hemostats and glass dissecting probes, a nine and four inch string, a cup of Ringers saline solution with an eyedropper, and a hook electrode. The software used to analyze and record the data was the BIOPAC system.
As far as I could remember I was never really any good at school. I couldn’t concentrate on things for no more than 5 minutes at a time I would either get discouraged or find it too easy and just give up. An author by the name of Carol Dweck wrote an article called “Brainology” in it Dweck describes that there are two types of mindsets fixed and growth. Those who are afraid to fail so they never try anything new are ones with a fixed mindset and the growth mindset are those who are not afraid to fail and find a new challenge an opportunity to learn something new. I guess you can say that I had a bit of a fixed mindset growing up I was always too scared to look stupid that I didn’t want to fail because I didn’t want to disappoint my siblings

I did not have to recruit anyone to do the picture due to the ability of the Samsung Galaxy Note 3 to take pictures using a voice command. I needed two pictures in order to make the replica. The first picture I propped the camera up and used the front facing camera. I positioned myself far enough away so that I could fit my whole body with my arms outstretched into the picture. When I reached this position I lifted both of my hands straight out to both sides of my body while turning my left leg so that the inside of my foot would be shown. Upon closer inspection to the picture I saw that I had to put my thumbs in the middle of each hand and also slightly bend the index finger of my right hand. I then continued to my second picture which was a lot harder. Since the second picture would have to be a picture of my limbs being able to fit into the circle person of the artwork I had to take this picture at an angle. To do so I used an envelope holder to get a forty-five degree angle and laid a wooden board forty-five degrees down on the opposite side of the camera. This time I had to take multiple pictures in order to get the right arm angles. After this I proceeded to download Gimp in order to edit the pictures. Since the angles were not right for two of my limbs I had to cut those out and layer it behind my first picture in order to get a decent portrayal of the picture. After
The autonomic nervous system (ANS) is largely regulated by autonomic reflexes and many of these reflexes; sensory information is transmitted to the hypothalamus and brainstem which are considered the control centers of our bodies (McCorry, 2006). Many of us have come to know the ANS as the involuntary nervous system. The ANS innervates cardiac muscle, smooth muscle, endocrine and exocrine glands; therefore it significantly contributes to homeostasis (McCorry, 2006). Most of the sensory input is from the thoracic and abdominal viscera and is transmitted to the brainstem by afferent fibers of the cranial nerve X which is the vagus nerve. After the input is integrated the response is carried out by the transmission of nerve signals of the preganglionic autonomic neurons. So what are some functions of the autonomic nervous system one may ask? Blushing (my favorite) is a response from the frontal cortex and involves vasodilatation of blood vessels to the face. Others may include fainting and a fast heart rate or increased blo...

These journals, published by some of the worlds leading universities, went through an intense editorial and peer- review process, stressing their integrity. This article referred to old references, dating back to 1960, as well as current references of 2015, allowing the audience to apprehend the impression that the study of neuroscience is an ongoing factor that has lasted for more than half a
Some students followed this procedure: Identify the external anatomy of these frogs, then pin the frog down dorsal side up, then cut the jaw to see the internals of the frog's mouth, see how the tongues flips, identify both the maxillary teeth as well as the vomerine teeth, put probe in the esophagus, and glottis. Next, identify the tympanum. Next, identify the cloaca and the spine. Next, cut from groins up to mouth just skin. The blade has to be parallel to the skin. After that, identify muscle striations where the muscles go and where they contract. Then cut the muscles. If there is a structure
The human body is divided into many different parts called organs. All of the parts are controlled by an organ called the brain, which is located in the head. The brain weighs about 2. 75 pounds, and has a whitish-pink appearance. The brain is made up of many cells, and is the control centre of the body. The brain flashes messages out to all the other parts of the body.
A scientist of 50 years ago investigating the brain’s functioning would have raised an eyebrow if someone had asked him or her what the field of Cognitive Neuroscience entailed simply because the field didn’t yet exist. During the 1960s, the new field of Cognitive Psychology developed methods for analysing behavioural cognitive relationships. Combining cellular neurobiological of Cognitive Neuroscience. It is a field that connects cognitive behavioural outcomes with underlying neural
Did you know that there are more nerve cells in the human brain than there are stars in the Milky Way, and that the heart beats around 3 billion times in the average person's life? Both of these facts have nothing to do with each other, but are part of very different and similar systems. One is the nervous system, and the other is the circulatory system. The nervous system receives information from your joints, muscles, and skin and sends the message to your brain to help you react, think, remember, and plan. The circulatory system moves blood and regulates temperature of your body.

For my project, I will be covering the nervous system. Some processes I will cover will be brain function in relation to nerves, and how age changes this. varies as people pass from childhood through adulthood to old age. From young age to adulthood, there is a spike in brain function, it steadies in adulthood, and then declines in old age, but different aspects of the brain change at different times. Since the nervous system is controlled by the brain, it is affected drastically. Some specific parts of the nervous system that I will explain will be the autonomic nervous system(made up of the sympathetic nervous system and the parasympathetic nervous system), and the enteric nervous system. I will go in depth into what makes these things work, by explaining the neuron-(I
