Basic Trivia Quiz On Brainstem!
The brainstem is an important part of the body as it has a lot of functions. It helps with eating, breathing, regulating heart rate and even sleeping! Test your knowledge on this organ by taking this quiz!
- 1.
In which part of the brainstem is the pons located?
- A.
Midbrain
- B.
Lowbrain
- C.
Hindbrain
- D.
It is not located in the brainstem
Correct Answer
C. HindbrainExplanation
The pons is located in the hindbrain. The hindbrain is a region of the brainstem that is responsible for various vital functions such as breathing, sleeping, and coordination of movement. It is located below the midbrain and above the medulla oblongata. The pons plays a crucial role in relaying messages between different parts of the brain and spinal cord, as well as in controlling certain reflex actions. Therefore, the correct answer is hindbrain.Rate this question:

Which arteries supply blood to the brainstem?
- A.
Basilar and vertebral
- B.
Pulmonary and umbilical
- C.
Coronary and systemic
- D.
Subclavian and maxillary
Correct Answer
A. Basilar and vertebralExplanation
The basilar and vertebral arteries supply blood to the brainstem. The basilar artery is formed by the fusion of the two vertebral arteries at the base of the brain. These arteries provide oxygenated blood to the brainstem, which is responsible for controlling vital functions such as breathing, heart rate, and consciousness.Rate this question:

The adult human brainstem emerges from how many of the primary vessels formed in the neural tube?
- A.
One
- B.
Three
- C.
Five
- D.
Two

How many main functions does the brainstem have?
- A.
One
- B.
Three
- C.
Six
- D.
Thirteen
Correct Answer
B. ThreeExplanation
The brainstem has three main functions. It is responsible for controlling the flow of information between the brain and the rest of the body, regulating basic functions such as heart rate and breathing, and coordinating motor movements. These functions are essential for the overall functioning of the nervous system and maintaining homeostasis in the body.Rate this question:

How many cranial nerves come from the brainstem?
- A.
Three
- B.
Twelve
- C.
Thirteen
- D.
Ten
Correct Answer
D. TenExplanation
There are ten cranial nerves that originate from the brainstem. These nerves are responsible for various functions such as sensory perception, motor control, and autonomic regulation of organs in the head and neck region.Rate this question:

What does the medulla oblongata do?
- A.
Controls breathing and heart rate
- B.
Controls sleeping
- C.
Controls reproduction
- D.
Controls eating
Correct Answer
A. Controls breathing and heart rateExplanation
The medulla oblongata is a part of the brainstem that controls various involuntary functions such as breathing and heart rate. It contains vital centers that regulate the rhythm and depth of breathing, as well as the rate and force of the heartbeat. These functions are crucial for maintaining homeostasis and ensuring the delivery of oxygen and nutrients to the body's tissues. Therefore, the medulla oblongata plays a critical role in controlling breathing and heart rate.Rate this question:

The brainstem harbors which of the following cranial nerves?
- A.
Cranial nerve IV
- B.
Cranial nerve III
- C.
Cranial nerve V
- D.
Cranial nerve X
Correct Answer
B. Cranial nerve IIIExplanation
The brainstem harbors cranial nerve III, also known as the oculomotor nerve. This nerve is responsible for controlling the movement of the eye muscles, including the muscles that control eye movement, eyelid elevation, and pupil constriction. It also plays a role in controlling the lens shape for focusing on near objects. The brainstem is a vital part of the central nervous system and is responsible for relaying information between the brain and the rest of the body.Rate this question:

What part of the brainstem does cranial nerve V come from?
- A.
Midbrain
- B.
Pons
- C.
Medulla
- D.
Cerebellum
Correct Answer
C. MedullaExplanation
Cranial nerve V, also known as the trigeminal nerve, originates from the medulla in the brainstem. The medulla is the lowermost part of the brainstem and is responsible for controlling vital functions such as breathing, heart rate, and blood pressure. The trigeminal nerve is responsible for transmitting sensory information from the face and controlling the muscles involved in chewing. Therefore, it makes sense that it originates from the medulla, which is involved in controlling many motor and sensory functions.Rate this question:

Which cranial nerve exits from the dorsal side of the brain?
- A.
Cranial nerve 1
- B.
Cranial nerve 2
- C.
Cranial nerve 3
- D.
Cranial nerve 4
Correct Answer
D. Cranial nerve 4Explanation
Cranial nerve 4, also known as the trochlear nerve, exits from the dorsal side of the brain. This nerve is responsible for controlling the superior oblique muscle of the eye, which helps with downward and inward eye movement. It is the only cranial nerve that exits from the dorsal side of the brain, making it the correct answer to the question.Rate this question:

What nerve wraps around the cranial nerve 6 before it exits the brain stem?
- A.
Cranial nerve 5
- B.
Cranial nerve 9
- C.
Cranial nerve 7
- D.
Cranial nerve 8
Correct Answer
C. Cranial nerve 7Explanation
The facial nerve, also known as cranial nerve 7, wraps around cranial nerve 6 before it exits the brain stem.Rate this question:
