Question

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

Explanation:

Muscle insertion is where a muscle attaches to a bone other than its origin. The biceps muscle attaches to the radius bone in the forearm as its insertion point. The triceps inserts on the olecranon process of the ulna. The gastrocnemius inserts on the calcaneus via the Achilles tendon. The deltoid inserts on the deltoid tuberosity of the humerus, not the scapula. The quadriceps insert on the tibia via the patellar tendon, not the femur.

Answer:

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