Functional Anatomy Flashcards
What are the functions of the Skeleton?
- Framework for body
- Attachment points for muscles
- Protects vital organs
- Stores essential mineral such as calcium and
phosphorus - Produces red blood cells in the bone marrow
What are Antagonistic Pairs?
As the agonist muscle contracts, the antagonist relaxes
What is an example is antagonistic pairs?
Biceps and Triceps, to contract, the triceps relaxes while the biceps contracts to lift the arm
What is the origin point of a muscle?
The bone that the origin of the muscle is attached to, does not move when muscle contracts
What is the insertion point of a muscle?
The bone that insertion is attached to moves more when the muscle contracts
What is muscle flexion?
Results in joint angle decreasing
e.g. flexing biceps
What is muscle extension?
Results in joint angle increasing
e.g. extending arm or leg
What is circumduction?
The circular movement of a limb
What is supination?
In the forearm, it refers to the turning of the forearm and hand so that the palm is facing up
In the foot, it refers to the outward roll of the of the foot during normal motion
What is pronation?
In the forearm it refers to the turning of the forearm and the palm so that the palm is facing down
In the foot it refers to the inward roll of the foot during normal notion
What is rotation?
A motion that occurs when a part turns on its axis
What is dorsi flexsion?
Movement which decreases the angle between the foot and the leg, so that the toes are brought closer to the shin
What is plantar flexsion?
Movement which increases the angle between the foot and the leg, so that the toes are take further away from the shin
What is abduction?
Movement away from the midline of the body (arms and legs)
What is adduction
Movement towards the midline of the body (arms and legs)
