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.
With reduced mobility, muscles can become floppy and make movement slower and more difficult, but when muscles are used on a regular basis, they remain firm and move more easily. When supporting moving and positioning activities, it is important to remember that muscles can only move the bones at a joint as far as the joint allows. For example, the elbow and knee joints have limited movement; trying to extend these joints beyond their range can cause painful damage to the joint. Nerve fibres run all the way through the body and send impulses to muscles, which enable the muscles to contract and relax. Nerve fibres are delicate structures and can easily become damaged through poor moving and handling techniques.
For example knees and elbow joints have limited movement and it is important to know how easy it is to these damage joints for example heaving people around a bed without using correct equipment or illegal lifting a person under their arms. When used correctly, hoists, turners and slide sheets are example of equipment which can be used to move and position individuals without having to cause injury. 1.2 There are many conditions that can have an impact on the correct moving and positioning of an individual such as: Arthritis, Parkinson’s disease, amputation, stroke, spinal injury and Cerebral palsy. Arthritis People will have stiff painful joints and will
Which type of bone provides a large, flat surface for muscle to attachment? b. A flat bone provides a large surface for muscle to attach. For example the hip bone and rib bones. 3.
However, X-Rays are largely used to examine broken bones. Jason is given an MRI scan rather than an X ray because a muscular disorder is suspected. 2. Why do Jason’s symptoms develop during the season and not during training? Answer: Excessive use of shoulder leads to inflammation and pain in the rotator cuff, the collection of muscles, tendons, and cartilage that stabilize the shoulder joint.
1. Understand anatomy and physiology in relation to moving and positioning individuals 1.1 Outline the anatomy and physiology of the human body in relation to the importance of correct moving and positioning of individuals: Muscles: - It is important to move an individual’s limbs safely, avoiding pushing or pulling roughly, as this may cause tendons and muscles to contract too strongly, overstretching or tearing them and causing strains. Joints: - Sprains may also occur in the ligaments, when a joint is forced either out of its normal movement range. There are three different types of joint: - Fixed joints, which have no movement (e.g. in the skull) - Cartilaginous joints, which have small amounts of movement (e.g.
In the bicep curl which produces flexion at the elbow, the biceps muscle is the agonist, as seen in the image below. Fixator: is a muscle that stabilizes or fixes a part of the body to which a muscle in the process of moving another part is attached. Function Detail Provide movement The action of muscles allows you to change position and move around. Maintain posture Believe it or not, standing upright is a very difficult thing for the body to do due to the fact that gravity is pulling you down the only reason you stay standing is because of the actions of the muscles. Produce heat The
Which minerals are stored in bones? The most important minerals that are stored in the bones are calcium and phosphorus. 2. Which types of bone provide a large, flat surface area for muscle attachment? Flat bones are generally thin and provides extensive surfaces for muscles attachment.
The muscles pull and move the bones of particular joints which then make the joints move and in turn the body then moves. We must also remember that joints like the knee and the elbow have only limited movement and trying to push past this limitation can cause damage to the joints which will be painful. 2. Strokes can cause permanent weakness or paralysis on one side of an individuals body when this happens it is important to know which side has been affected by the stroke and how to move that individual without causing them pain. Individuals suffering from arthritis can often be left with stiff and painful joints and frequently have limited movement in the affect areas.
Susan underwent disuse atrophy because it was immobilized so it did not perform the same amount of work as usual. In order to stop this from happening you would have to stimulate the muscles. Small contractions would have been weak enough to not disrupt the alignment of the third metatarsal. Performing isometric muscle contractions while her foot in the cast could possibly prevent the loss of muscle mass. 8.
