Question
The calcaneus is the insertion for which muscle?
Group of answer choices:
- gastrocnemius
- semitendinosus
- trapezius
- gracilis
Solution
The calcaneus, commonly known as the heel bone, serves as the insertion point for the gastrocnemius muscle. The gastrocnemius is one of the major muscles of the calf, and it connects to the calcaneus via the Achilles tendon. This allows it to play a crucial role in movements such as walking, running, and jumping.
In contrast:
- Semitendinosus: This muscle is one of the hamstrings and does not insert on the calcaneus.
- Trapezius: This is an upper back muscle and is not associated with the calcaneus.
- Gracilis: This muscle is part of the inner thigh and also does not insert on the calcaneus.
Thus, the correct answer is gastrocnemius.
