Question

lo 5.2. what is an example of a muscle insertion? biceps muscle attaching to the radius bone in the forearm deltoid muscle attaching to the scapula bone in the shoulder triceps muscle attaching to the ulna bone in the forearm gastrocnemius muscle attaching to the calcaneus bone in the foot quadriceps muscle attaching to the femur bone in the thigh

Explanation:

Muscle insertion is where a muscle attaches to a bone that moves when the muscle contracts. The biceps muscle attaches to the radius bone in the forearm and helps in forearm - flexion. The deltoid attaches to the humerus (not scapula for insertion). The triceps attaches to the olecranon process of the ulna. The gastrocnemius attaches to the calcaneus via the Achilles tendon and helps in plantar - flexion. The quadriceps attaches to the tibia (not femur for insertion).

Answer:

A. Biceps muscle attaching to the radius bone in the forearm
