Hello Nellie! Your Auntie Rayna here! I heard from Aunt Gladys that both of you were making fried chicken, and it made you wonder about how broken bones heal. I, also, heard you were wondering how bones grew after you saw some unborn chickens and their broken eggs. I’d love to tell you how our bones heal, but first, let’s go over how they begin their “life” cycle into becoming an actual bone. When we are born, our bones start out as hyaline cartilage (hyalos- meaning glass). You can think of hyaline
In the Forensic Case #356228, skeletal remains of both human and animal were discovered in a hunting area. The skeletal remains were of potential victims named as either Robert Rutherford or Stephen Morton. Robert Rutherford, potential victim #1, was an African American, 65 years or age, had a pacemaker, carried a Gerber 650 knife, had unknown religious affiliations, and was 5’ft 6”inches tall. Potential victim #2, was Stephen Morton, a Caucasian 40 years of age, had a heart condition, was a hunter
Intramembranous ossification mainly occurs during the formation of the flat bones of the skull, as well as the mandible, maxilla, and clavicles. The bone is formed from connective tissue such as mesenchyme tissue rather than from cartilage. The bone is formed from connective tissue such as mesenchyme tissue. Stem cells, mesenchymal initiate the process of intramembranous ossification. A small cluster of mesenchymal cells will begin to replicate and
his team studied the timing of reduction and ossification in several species of birds (Chicken, Mallard duck, and Chilean tinamou) (Botelho, 2016). They specifically looked at the molecular development of cartilage maturation and growth plate formation in the tibia and fibula. The key protein being Indian hedgehog (IHH) that was originally found in hedgehogs codes is produced by prehypertrophic chondrocytes. Its main role is endochondral ossification in most animals. It stimulates immature chondrocytes
Keratinized Stratified Squamous Epithelium (White Skin): Vertical Section (Slide 7) List of Tissue: This section shows white skin which is composed of keratinized stratified squamous epithelium. The structures of the white skin includes the keratinized stratified squamous epithelium, merocrine sweat glands, apical (free) surface, basal membrane, sebaceous gland, dense irregular connective tissue, collagen fibers in bundles, a blood vessel, and nuclei of the epithelium. Description of the tissues:
The skeletal system helps with endocrine regulation, protection, support, movement, calcium storage, and blood cell production. The skeletal system consists of 206 bones, in the adult human body, all of which are divided into two major divisions. One division, the axial skeleton made up from 80 bones, runs along the body’s midline and the other division, the appendicular skeleton which has 126 bones. 80 percent of the human skeleton is made up of compact bone, which is dense and filled with organic
The Integument: List the embryonic germ layers that the epidermis and dermis are derived from (be specific for the dermis). (2 points) Dermis is derived from the mesoderm. It is made up of layers of cells that originate from the bottom most layer called the stratum basale, which is constantly undergoing mitosis. The epidermis is derived from the ectoderm. The development of hair, feathers, teeth, and scales all depend on the same structure. What is it called? (2 points) Dermal papilla How
blood cell production, storage for calcium and endocrine regulation. Bone serves as the basic unit of the human skeletal system. Ossification is characterized as a process that produces new bone. This process is also known as bone formation. Bone formation consists of two types of development. They are intramembranous and endochondral formation. Intramembranous ossification takes place when cells within the membrane change and become osteochondral progenitor cells.
is contained within the medullary cavity and is a soft tissue. Skull bones and much of the clavicle are flat bones produced by intramembranous ossification, a process by which a membrane of soft tissue becomes ossified, subsequently producing another membrane which becomes ossified, which gives flat bones their layered appearance. Endochondral ossification is a process of bone development that begins in a fetus of about 6 weeks old and lasts until more than 20 years after birth. Bones grow both
Achondroplasia (ACH) is the most common form of short-limb dwarfism occuring in 1 in 15,000 to 28,000 births and appears to be slightly more prevalent in females, but indiscriminent toward race (1-3). Evidence has been found in Egypt for cases of ACH dating back as far as 4500 B.C. (4). In simplest terms, ACH is a disease where the dwarfing of bones formed in the cartilage occurs (5). There are many features that accompany this disease including rhizomelic (proximal) shortening of the extremities
The human body is made up of 12 different systems. Each system has a separate function while some do work together. One system is called skeletal system which is to serve as a support the body, mineral storage, energy storage (fat), blood cell production, movement (leverage), and protect the internal organs. (Martini, 112). With the help of the muscular system, it keeps us moving and makes us to do tasks that we don’t think about like swinging the arms while running. The average adult skeleton has
signals its importance to blood cell reproduction. An embryos skeleton is made up mostly of cartilage; cartilage is later replaced by bone over the years, through a process called ossification. The two types of ossification are intramembranous ossification that develop membranous bone and endochondral ossification that develops cartilaginous bone. Cartilage is located in places like your ears and nose, cartilage is also found near the ribs in order to expand whenever you breathe. Joints consists
2.1.1.a Flexor Tendon and Rotator Cuff The ability to flex the finger consists of a serial of flexor muscles in the forearm and their tendons are inserted to the bones of finger. The injury of flexor tendon might cause the loss of bending of the fingers or thumb. The flexor digitorum profundus tendon (FDP) attaching to the distal phalanx and the flexor digitorum superficialis tendon banding to middle phalanx well demonstrated the specific type of tendon-to-bone insertion site characterized by the
Rickets is a bone disease that occurs in children as a result of a Vitamin D deficiency. This disease, which was nearly eradicated in the early 20th century, has become a re-emerging health concern for various countries in the past ten years. Certain factors such as poor nutrition as a result of low socioeconomic status or high concentrations of melanin in the skin can increase the chances of getting rickets. Sufficient Vitamin D levels are crucial to the functioning of the body, especially in the
