Ligaments support and stabalize the an individuals joints. A strain is an injury that occurs to a muscle and/or tendon. Tendons are fibrous cords of tissue, which connect muscles to bone (Muscle of the Foot and Ankle, n.d). 2. What bones form the articulation (joint) of the ankle?
5. 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 bones of the body are formed by this process. 6.
also called voluntary muscles, are the muscles that attach to bones that we consciously move. 50 Striations-alternating light and dark bands recognizable on skeletal muscles 51 Muscle Sense-the brain's ability to sense where the muscles are and what they are performing during movement 52 Stretch Receptors-work in conjunction with the sensory receptors, also referred to as proprioceptors. Senses the changes in the length of a muscle as it stretches. 53 Origin-end of the skeletal muscle attached to the immovable part of the bone 54 Insertion-end of the muscle attached to the movable part of the bone 55 Prime Mover-a muscle that does most of the work during movement 56 Synergist-muscles that contract and assist the prime mover 57 Antagonists-muscles that resist the prime mover's action and work to cause action in the opposite direction 58 Tendons-composed of parallel fibers kept together by a connective tissue sheath 59 Myosin-thick filament that makes up approximately one half of the proteins that occur in muscle
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.
The human skeleton Is made up of 206 bones. The functions of the skeleton are to provide support, give our bodies shape, and provide protection to other systems and organs of the body, to provide attachments for muscles, to produce movement Joints A joint is the point where two or more bones meet. There are three main types of joints; Fibrous (immoveable), Cartilagenous (partially moveable) and the Synovial (freely moveable) joint. Fibrous joints Fibrous (synarthrodial): This type of joint is held together by only a ligament. Examples are where the teeth are held to their bony sockets and at both the radioulnar and tibiofibular joints.
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.
1- Which minerals are stored in bones? (five minimum) The minerals that are stored in your bones are calcium, phosphorus, potassium, iron, and zinc. 2- Which type of bone provides a large, flat surface area for muscle attachment? The type of bone that provides a large, flat surface area for muscle attachment in a flat bone. 3- Describe the [location, composition, and function] of the epiphyseal plate.
Compare and contrast Cardiac and Skeletal Muscle. Discuss how their differences enable them to carry out their function more effectively. Skeletal, cardiac and smooth muscle account for nearly half of our body weight, their roles essential for normal bodily function. Skeletal muscles; attached to the skeleton via tendons; maintain body posture, are voluntary controlled and have antagonistic arrangement for muscular contractions. They tend to enlarge following vigorous exercise, a phenomenon called muscular hypertrophy and are located around the body.
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.
Provides skeletal support. * b. In most vertebrates, it’s replaced by a jointed skeleton. * c. Remains of the notochord exist as disks between the vertebrae. 2.
