Muscle Group Case Study
1. Describe the main muscle groups of the body and their function
There are three main categories that the muscles in the human body fall into:
• Skeletal Muscle
Skeletal muscle is the foremost area of concern for a sports masseuse. The main functions of this muscle group is to move the body in a voluntary manner, for example, if you want to kick a ball you will voluntarily have to send a signal through your brain to inform the muscles in your legs to contract/flex/extend and execute the skill. In this case the main areas of examination for a sports masseuse will include the upper and lower legs, and abdominal areas while generally, other key skeletal muscular areas are the chest, back and arms (Anon, 2012, p. 10). These areas of concern …show more content…
It is located between the shoulder joint and elbow joint. The biceps and triceps surround the humerus bone.
The lower arm contains two bones; the radius and ulna. These two bones connect between the elbow joint and wrist and allow the twisting motion of the forearm; pronation and supination.
• Leg
The main bone in the upper leg is the femur. This is the longest bone in the body. A ball and socket joint connects the femur to the pelvis and the kneecap. The femur allows the basis for movement, working closely with the bones and muscles in the lower leg and the pelvis area.
The patella (or knee cap) is the bone situated at the bottom of the femur bone. It protects the joint and also promotes leverage for extension of the joint.
The lower leg comprises of two main bones; the tibia and fibula. The tibia (or shin bone) is the second longest bone of the body. It provides the basis of support for the lower leg and body in general. The fibula assists the tibia in this process.
4. Explain the different joint types in the body.
A joint is the point where two or more bones meet. Within the human body there are three main categories of …show more content…
This type of joint allows the vertebral bones to slide and glide across each other in several directions, thus allowing a wide range of movement within the joint.
II. Hinge Joint
The hinge structured joint allows for flexion and extension, the knee and elbows being primary examples.
III. Pivot Joint
The atlas and axis are bones situated within the neck. The pivot allows rotation of one bone around another as what happens when looking from side to side.
IV. Saddle Joint
The saddle joint allows for a greater variety of movement options in comparison to the hinge joint; flexion, extension, adduction, abduction and circumduction. The sternoclavicular joint is an example of this.
V. Condyloid Joint
This joint has the same movements as the saddle joint and allows for example, the wrist joint, the capacity to travel along two planes.
VI. Ball and Socket Joint
The ball and socket joint allows for a relatively free range of movement. For example, the head of the femur is fixed into the shallow bowl like shape in the pelvis which allows it to move in almost any direction, including internal and external rotation. (Anon, 2012)
