- One of the following is considered as a part of anterior cervical vertebral muscles:
- A.
Semispinalis capitis
- B.
Longus capitis
- C.
Splenius capitis
- D.
Obliques of the head
Correct Answer
B. Longus capitisExplanation
The longus capitis muscle is considered as a part of the anterior cervical vertebral muscles. It is located in the neck region and helps to flex the head and neck. This muscle originates from the anterior tubercles of the transverse processes of the third to the sixth cervical vertebrae and inserts onto the basilar part of the occipital bone. Its main function is to assist in the movement of the head and neck, particularly in flexion.Rate this question:

The type of joint that is located between basilar occipital bone and body of sphenoid bone is:
- A.
Synovial joint
- B.
Fibrous Joint
- C.
Primary cartilaginous joint
- D.
Secondary cartilaginous joint
Correct Answer
C. Primary cartilaginous jointExplanation
The joint between the basilar occipital bone and body of the sphenoid bone is a primary cartilaginous joint. Primary cartilaginous joints are connected by hyaline cartilage, which allows for limited movement. In this specific joint, the hyaline cartilage between the occipital bone and sphenoid bone allows for slight movement and flexibility.Rate this question:

The artery that passes directly below the weakest point of the skull is
- A.
Anterior division of middle meningeal artery
- B.
Posterior division of middle meningeal artery
- C.
Accessory meningeal artery.
- D.
Anterior meningeal artery
Correct Answer
A. Anterior division of middle meningeal arteryExplanation
The correct answer is the Anterior division of middle meningeal artery. The middle meningeal artery is a branch of the maxillary artery, and it enters the skull through the foramen spinosum. The anterior division of the middle meningeal artery passes directly below the pterion, which is considered the weakest point of the skull. This area is vulnerable to injury, and damage to the artery can lead to an epidural hematoma.Rate this question:

Which of the following openings can be seen from the inferior view of the skull but NOT from endocranial view:
- A.
Jugular foramen.
- B.
Carotid canal
- C.
Foramen spinosum
- D.
Foramen rotundum
Correct Answer
B. Carotid canalExplanation
The carotid canal can be seen from the inferior view of the skull but not from the endocranial view because it is located on the external surface of the skull, specifically on the petrous part of the temporal bone. The endocranial view refers to the internal surface of the skull, which does not provide a direct view of the carotid canal.Rate this question:

Which of the following cervical spinal nerve does NOT have any sensory contributions
- A.
C4.
- B.
C3
- C.
C2
- D.
C1
Correct Answer
D. C1Explanation
C1 is the correct answer because it does not have any sensory contributions. The cervical spinal nerves typically have both sensory and motor functions, but C1 is an exception. It is primarily a motor nerve that innervates the muscles of the neck and does not provide any sensory input. The sensory contributions for the other options (C2, C3, and C4) are present, making them incorrect answers.Rate this question:
