It allows ability of turning the head from side to side. Ball and socket joint- a joint where a ball shaped surface of a rounded bone fits into a cup like depression of another. The rounded head of the humerus rest on the socket of the shoulder blade allowing you to swing your hands. Hinge joint- it allows movements similar to the opening and closing of a hinged door. The elbow joint allows for the extension and flexion of the forearm relative to the upper arm as well as rotation of wrist and forearm. Ellipsoid joint- it allows the extending and bending movements rocking from side to side but rotation movements are limited.

Saddle joint- bones in this joint can rock forth and back as well as from one side to another but have limited rotation. The joint in the thumbs is the only saddle joint. Gliding joint- bones move by gliding against each other. It occurs between surfaces of two bones that are flat held together by ligaments. (Word count 200) Question 4- describe the structure of a named synovial joint. The hip synovial joint The hip joint is a ball and socket that allows individuals to run, walk and jump.

It is among bodys the most flexible joints. It allows a range of motions compared to other joints in the body with an exception of the shoulder joint. It is formed between the hipbone and the femur. It has a round cup structure on the hipbone referred to as the acetabulum that forms the socket for the joint. The femurs head is rounded in shape to constitute the ball of the joint (Yoon et al. 2011, 309). It is lined by hyaline cartilage lining the head of the femur and acetabulum to provide a smooth surface for gliding bone movement.

The hyaline is also a shock absorber preventing the collision of bones during movement. The joint contains synovial membranes between the layers of the cartilage that are important in secreting the synovial fluid to lubricate the joint capsule. Tough ligaments preventing the joint dislocation surround the joint. Strong muscles around the joint preventing dislocation also hold it together. The ball and socket structure is important as it allows the femur to move through a 360-degree circle.

The femur also has an ability of rotating around its axis in a 90-degree angle at the joint (Pacifici et al. 2005, 241). (Word count 210) TASK 2 Question 1- Explain the structure of a voluntary muscle using a fully labeled and referenced diagram. A skeletal muscle is a voluntary muscle also called a striated muscle as a result of its appearance.
