1.Name 3 different types of sensory receptors.(544) The special sensory receptors are distinct receptor cells and mostly are modified nerve endings of sensory neurons, they are located within the complex sensory organs like the eyes and ears or in the epithelial structure of taste buds. The 3 types are exteroceptors, interoceptors and proprioceptors.
EXTEROCEPTORS: RECEIVE FROM OUTSIDE THE BODY.
INTEROCEPTORS: RECEIVE FROM INSIDE THE BODY
PROPRIOCEPOTORS: UNCONSCIOUS INFORMATION
2.What are general senses versus special senses? Special senses are the sensations such as taste, smell, hearing, sight only in special sense organic in the head region. General senses are touch pain, pressure, temperature and tension on the skin.
3.Name the 4 types of stimulus that excites receptors for general senses. Give examples for locations you would find these receptors.
Visual:Cerebral cortex
Olfactory: Temporal lobe.
Auditory: Temporal lobe
Gustatory: Gyrus
4.Name the locations you would find the special sensory receptors.
Visual is in the rods and cones of the retina. Olfactory is the hair cells located in the mucous

The four rectus muscles originate from common tendinous ring which is at the back of the orbit and the location and movement is is that they promote clearly indicated by their names which is superior, inferior and lateral, and medial rectus muscles. The actions of the two oblique muscles is that they are less easy to deduce because they take weird paths to the orbit. They move the eye in a vertical plane when the eyeball is already turned medially by the rectus muscles. Superior oblique muscles originates in common with the rectus muscles that goes along the medial wall of the orbit and then makes a right angle to fibrocartilage loop called trochlea. The inferior oblique muscle originates from medial orbit surface and runs laterally and oblique to insert on the inferolateral surface of the
The origin of the triceps brachii is also from the scapula like the biceps brachii. In a mink, the extensor digitorium originates on the lateral epicondyle of the humerus yet in humans it is present in the posterior forearm and is responsible for extending the phalanges, wrist, and elbow in both species. Anothier muscle with similar functions to the extensor digitorium is the flexor carpi ulnaris but instead it is soley responsible for flexin... ... middle of paper ... ...

This is extremely simplified, but it will suffice for now. Photoreceptors are tiny, specialized neurons located in the retina at the back of the eye. There are two types of photoreceptors, rods and cones. Each follow the same principles: when light hits them they respond with a chemical reaction using a substance known as rhodopsin. Once this reaction occurs, a chain of events sends this message down a number of sophisticated and specialized neurons, eventually reaching the brain and resulting in what we call sight.
involves all of the five senses, the way we perceive them. Perception is not restricted to

Senses are any of the abilities in which stimuli external of the body are acknowledged and experienced, this includes the abilities of sight, hearing, smell, touch and taste. Our senses are an imperative foundation of information regarding the world around us, which rather passively reflect reality actively structured around it. Perception includes two main components, sensation and interpretation; one’s understanding of something stems from the information provided by their senses. As humans, we rely on our sense perception to differentiate between what is real and what isn’t, we accept the reality that has been offered to us. Our life is as real as we believe it to be,
Another sense of organ that I witness in my grandma is hearing impairment. As she is aging she experience gradual decrease in how she can hear people when they talk, but when we are talking to her, we usually move close to her so that she can hear our words clearly. I understand that earing loss is one of the most common conditions affecting older and elderly. When it comes to small, taste, touch, and pain in older people, I am not knowledgeable in that aspect.
We use our ears for the hearing sense, and we use our eyes for vision.
Television Commercials targeted to Minorities The first commercial television advertisement ran almost 76 years ago and it featured the “Bulova” watch brand. Since then, commercials have been considered one of the premier forms of advertising. A multitude of advertisers have used symbols from the Native American heritage and traditions to sell their products.
Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.
Visual perception and visual sensation are both interactive processes, although there is a significant difference between the two processes. Sensation is defined as the stimulation of sense organs Visual sensation is a physiological process which means that it is the same for everyone. We absorb energy such as electro magnetic energy (light) or sound waves by sensory organs such as eyes. This energy is then transduced into electro chemical energy by the cones and rods (receptor cells) in the retina. There are four main stages of sensation. Sensation involves detection of stimuli incoming from the surrounding world, registering of the stimulus by the receptor cells, transduction or changing of the stimulus energy to an electric nerve impulse, and then finally the transmission of that electrical impulse into the brain. Our brain then perceives what the information is. Hence perception is defined as the selection, organisation and interpretation of that sensory input.
First, one must have the five senses; taste, smell, hear, see, and feel. Yes, these are physical aspects, however, these senses are what any human needs to be, human. For example, the human body needs to be able to taste. It must ingest food, and the food must appeal to a decent taste. A human must also be able to smell, so one may smell a poisonous gas, delicious food, or any other stench that may linger in the air. To be able to hear, enables the human to hear danger or a noise that appeals to them. When seeing, danger is also noted as well as the care of others. When one feels, the object that is being felt may make the person feel comfortable. Not only the sense of touching, but feelings.
The nose can smell thanks to the ten million scent receptors that make up the Olfactory Epithelium(smell device). The Olfactory Epithelium is located about 7 cm up inside the nose.These receptors can differentiate from over 10,000 different smells. The receptors send signals to the Olfactory Bulb. Those signals then travel to the brain which interprets what you are smelling by combining the different signals of the receptors. Many parts of the brain are affected by these signals.
...ferent muscles the largest happens to be a skeletal muscle called gluteus maximus and the hardest working muscle is in the eye.
The five senses of sight, hearing, touch, taste and smell are all sensations throughout the human body. Sensation is the involvement of sensory receptors as well as the central nervous system in order to allow us to experience outside stimuli. The system that allows us to experience sensation is the sensory system.
