Which ossification method would form a femur? Endochondral ossification 6. Why is bone remodeling necessary when a person reaches adulthood? Bone remodeling allows for new osseous tissue to replace older osseous tissue before deterioration sets in. It also allows for bones to heal and creates a stronger bone.
Which has an elongated shape? Ans: pg. 173 – a) short bone; b) long bone 4. Which type of bone provides a large, flat surface area for muscle attachment? Ans: pg.
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.
Timothy Stephenson Course : Access to Higher Education Diploma Subject : Biology Unit Title : Anatomy and Physiology of the Human Skeleton and Muscles TAQ 1 The features of Skeletal and Bone which enable them to carry out their roles The adult human skeleton consists of 206 bones, these bones are made up of several living tissue which contain blood vessels and nerves. There are two types of bone, Cortical which is very compact and makes up the shaft of bones and the Cancellous which is located at the ends of the long bones. The diaphysis is the main shaft in a typical long bone, such as the Humerus, it is formed of Cortical bone and contains Nutrient arteries and the hollow inside is filled with fatty yellow bone marrow. The epiphyses which are the distal and proximal ends of the bone is formed of Cancellous bone and contain spongey bone and red bone marrow which is used for the production of new red blood cells. The epiphyses of each end are covered in is a thin layer of hyaline cartilage which is known as the articular cartilage, this reduces friction between joints when movement is carried out.

g. From the Synovial Joint page, click structural subtypes of synovial joints. Locate body examples of the following joints and describe the movement of each. Condyloid: This is an oval shopped articulating surface where one bone fits into a depression of another bone. Planar: This is a plane joint with no axil in which the articular surface is flat or only slightly curved. This allows slipping or gliding movements.
Why would Stefan think that an enlarged right deltoid tuberosity might indicate right-handedness? More attachment points for tendons and ligaments to form, indicating more muscle on that side, which could be an indication of the dominant side. 5. What is the location of the pubic symphysis of the female skeleton in the story? Medial in the center of the pelvis, where the two pubis bones meet.
Assignment 3:Neuroanatomy Project Physiological Psychology | PSY350 A03 Name: Instructor: Date: The CNS or central nervous system is the foundation of our existence. It controls many interact details that make us unique. Such as our personalities, senses, movements, as well as other functions like heart beat, breathing, and blood pressure. The CNS is encased in bone just as the brain is encased in skull and the spinal cord is encased in the vertebral column. The vertebral column is a structure of bone that is located in the back that encases the spinal cord from top to bottom in order to protect it from injury.
Dermis is mainly connective tissue, is deep to the epidermis, and is vascular * The skin contains collagen (for strength) and elastic (for stretch) fibers. * The skin is thicker on the posterior than the anterior parts of the body; thicker on lateral parts of limbs than medial parts. —Subcutaneous layer (or hypodermis) is deep to dermis, but is not part of skin. It is mainly adipose tissue B. Layers of epidermis (from deepest to superficial) 1. Stratum Basale (= base) a. has stem cells that continuously divide by mitosis
