Questions and Answers
- 1.
The foramen magnum is located in this bone.
- A.
Occipital
- B.
Temporal
- C.
Sphenoid
- D.
Ethmoid
Correct Answer
A. OccipitalExplanation
The foramen magnum is a large opening at the base of the skull through which the spinal cord passes. It is located in the occipital bone, which is situated at the back of the skull. The occipital bone forms the posterior part of the cranial cavity and provides protection for the brain. It also articulates with the first cervical vertebra, allowing for movement of the head.Rate this question:

The mandible articulates with this bone.
- A.
Sphenoid
- B.
Temporal
- C.
Maxillae
- D.
Zygomatic
Correct Answer
B. TemporalExplanation
The mandible articulates with the temporal bone. The temporal bone is located on the side of the skull, and it forms the lower part of the skull and the upper part of the jaw. It contains the temporomandibular joint, which allows for the movement of the mandible. Therefore, the mandible and the temporal bone have a direct articulation and work together for jaw movement.Rate this question:

The thinnest portion of cranium is located here.
- A.
Cribriform plate
- B.
Frontal sinus
- C.
Occipital condyle
- D.
Saggital suture
Correct Answer
A. Cribriform plateExplanation
The cribriform plate is a part of the ethmoid bone located in the skull. It is a thin, sieve-like structure that separates the nasal cavity from the brain. The cribriform plate is the thinnest portion of the cranium and is responsible for transmitting the olfactory nerves, which are responsible for the sense of smell. It is delicate and fragile, making it susceptible to damage in cases of head trauma.Rate this question:

How many bones are there in the vertebral column?
- A.
24
- B.
20
- C.
22
- D.

D. 26Explanation
The correct answer is 26. The vertebral column, also known as the spine, is made up of 26 bones called vertebrae. These vertebrae are stacked on top of each other and provide support and protection for the spinal cord. Each vertebra has a unique shape and function, allowing for flexibility and movement while maintaining stability. Therefore, the correct answer is 26.Rate this question:

- A.
Mastoid sinuses
- B.
Sphenoid sinuses
- C.
Maxillary sinuses

Frontal sinuses
Correct Answer
C. Maxillary sinusesExplanation
The maxillary sinuses are the largest sinuses in the skull. They are located in the maxillary bones, which are the cheekbones. These sinuses are responsible for producing mucus that helps to moisturize and filter the air we breathe. They also play a role in reducing the weight of the skull and providing resonance to our voice.Rate this question:

The number of cervical vertebrae in the spinal column are _____
Correct Answer
7
sevenExplanation
The number of cervical vertebrae in the spinal column is 7. This is a well-known fact in anatomy. The cervical vertebrae are the seven vertebrae that make up the upper part of the vertebral column, located in the neck region. They provide support and flexibility to the neck and head. The use of the word "seven" in the answer reinforces the correct numerical value of 7 for the number of cervical vertebrae.Rate this question:

This cranial bone articulates with all other cranial bones _____
Correct Answer
sphenoidExplanation
The sphenoid bone is a butterfly-shaped bone located at the base of the skull. It is considered the "keystone" bone of the cranium because it articulates with all other cranial bones. This means that it forms joints with the frontal, parietal, temporal, occipital, and ethmoid bones, contributing to the overall structure and stability of the skull.Rate this question:
- 8.
Your ear hole is located in parietal cranial bone.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because the ear hole, also known as the external auditory meatus, is not located in the parietal cranial bone. Instead, it is located in the temporal bone of the skull. The temporal bone is situated on the sides and base of the skull, housing various structures of the ear, including the ear canal or external auditory meatus.Rate this question:
