3. Describe the location, composition, and function of the epiphyseal plate. The epiphyseal plate is a layer of hyaline cartilage that allows the bone to grow in length. It is located in the Metaphysis of the growing bone. When the bone is finished growing, the hyaline cartilage is turned into osseous tissue.
2. the portion of a long bone formed from a primary center of ossification. EPIPHYSIS- 1. The end of a long bone that is originally separated from the main bone by a layer of cartilage but that later becomes united to the main bone through ossification. HYALINE CARTILAGE- a type of connective tissue composed of specialized cells in a translucent, pearly blue matrix. Hyaline cartilage thinly covers the articulating ends of bones, connects the ribs to the sternum, and supports the nose, the trachea, and part of the larynx.
3- Describe the [location, composition, and function] of the epiphyseal plate. The epiphyseal plate is located in the metaphysis and is composed of hyaline cartilage. It is the growth plate, it covers the part of the epiphysis where the bone forms an articulation with another bone. It reduces friction and absorbs shock in articular cartilage. In the periosteum it surrounds the bone surface wherever it is not covered by articular cartilage, it is a sheath of dense irregular connective tissue containing osteoblasts, it functions to protect the bone, assists in fracture repair, nourishes bone tissue, and serves as an attachment point for ligaments and tendons.
Which ossification method would form a femur? The femur, which is a long bone, is formed by endochondral ossification which is the replacement of cartilage by osseous tissue. most of the long bone body are formed by this process. 6. Why is bone remodeling necessary when a person reaches adulthood?
Essay shows the importance of bones in human body and their main role, tasks they accomplish every day. Skeletal function Six functions of the skeleton: Support: Provides structural support for the entire body Protection: Surrounds soft tissue- ex. ribs and sternum protect the heart and lungs, - skull protects the brain Movement: Skeletal muscle is attached to bone so it pulls on the bone when it contracts Mineral homeostasis: Stores calcium and phosphorus--minerals are released into the blood when needed Blood cell production: Red bone marrow produces red blood cells, white blood cells and other blood elements. Storage: Storage of minerals and lipids (fats)-yellow marrow stores fat-(found in long bones) Bone. Definition: Bones are rigid organs that constitute part of the endoskeleton of vertebrates.
1. Why osseous tissue is considered a connective tissue? a. Osseous tissue is considered connective tissue because just like connective tissues, osseous tissue contains an abundant extracellular matrix that surrounds widely separated cells. 2. What is the path a nutrient would travel through compact bone tissue from its diffusion out of a blood vessel in the periosteum to an osteocyte located within the second osteon in from the surface of the bone?
The bone growth progresses from the top downward, just as bones grow in fetuses. The child will soon start to grow bones starting at the neck, then on the shoulders, arms, chest area and finally the feet. Some doctors have noticed that FOP involvement is typically seen first in the dorsal, axial, cranial and proximal regions of the
Intertrochanteric refers to the area of a bone that rests between trochanters. 2. Draw a picture of what you think Margaret's fracture looks like. Case Study 6 - Bones 3. The radiologist reported signs of osteoporosis.
Magnesium-based implants will be used for fixing the fracture. Then the operated limb was immobilized by a cast for six weeks. After the end of eight weeks and twelve weeks, the rabbits were euthanized and the samples were assessed mechanically by tensile testing. After the mechanical testing, the samples were embedded and sectioned for histological
6. Why is bone remodeling necessary when a person reaches adulthood? h. Bone remodeling is necessary when a person reaches adulthood to renew the osseous tissue before deterioration sets in. It heals injured bones and redistributes bone along the lines of mechanical stress 7. Which marking of the skull articulates with the first cervical vertebra?
