Final answer:
The semispinalis cervicis muscle inserts at the spinous processes of the C2-C5 vertebrae in the cervical region of the spine.
So, the correct answer is option 2.
Step-by-step explanation:
The student is inquiring about the insertion of the semispinalis cervicis, which is a muscle in the human body that is part of the transversospinales group. The transversospinales muscles, including the semispinalis muscles, run from the transverse processes to the spinous processes of the vertebrae.
Specifically, the semispinalis cervicis, named for its association with the cervical region of the spine, inserts at the spinous processes of the C2-C5 vertebrae. The cervical vertebrae have unique features such as a small body, bifid spinous processes, and transverse processes that have a transverse foramen. The atlas (C1) and axis (C2) are also part of this group but have distinct anatomical characteristics mentioned in the question.
So, the correct answer is option 2.
Complete question:
The insertion of the semispinalis cervicis is:
- T1-T5 transverse process
- C2-C5 spinous processes
- Occiput
- Atlas Transverse Process
