What is circumduction?
Circumduction is the circular movement at a joint, combining flexion, extension, abduction, and adduction. An example is the movement of the arm in a circular motion.
What are dorsiflexion and plantarflexion?
Dorsiflexion is the movement that brings the top of the foot toward the shin, while plantarflexion is the movement that points the toes away from the shin.
What is rotation in terms of joint movement?
Rotation is the movement around a central axis. For example, turning the head from side to side involves rotational movement.
Provide an example of a joint movement involving adduction.
Bringing the legs back together after a side-step is an example of adduction.
Define abduction in terms of joint movement.
Abduction is the movement of a body part away from the midline of the body.
What is the role of tendons in the body?
Tendons connect muscle to bone, transmitting the force generated by muscles to move the bones.
What is the function of ligaments?
Ligaments are tough bands of connective tissue that connect bone to bone, providing stability to joints.
Give an example of a joint movement involving extension.
Straightening the elbow is an example of extension, where the angle between two body parts increases.
What is flexion?
Flexion is a movement that decreases the angle between two body parts, usually bending a joint.
Name the three main types of joints in the human body.
The three main types of joints are hinge joints (e.g., elbow), ball and socket joints (e.g., shoulder), and pivot joints (e.g., neck).
What is a joint?
A joint is a point where two or more bones meet, allowing movement and flexibility.
