1.
What are the main parts of the Central Nervous System?
Correct Answer
A. The Brain and Spinal Cord
Explanation
Our Central Nervous System Consist of only two parts, The Brain and Spinal Cord.
2.
Which Systems are included in the Peripheral Nervous System?
Correct Answer
D. The Somatic and the Autonomic Systems.
Explanation
The Peripheral Nervous System contains two parts, the Somatic and the Autonomic System.
3.
The Somatic System includes the sensory nerves that keep the body in touch with the outside world, along with the nerves that make or govern bodily responses to that world.
Correct Answer
A. True
Explanation
The statement accurately describes the Somatic System, which consists of sensory nerves responsible for relaying information from the external environment to the brain, as well as motor nerves that control voluntary movements and bodily responses. Therefore, the answer "True" is correct.
4.
Is it possible for the Brain go without oxygen for 40 minutes or more?
Correct Answer
A. True
Explanation
A child falls into an icy lake, is pulled out 40 or more minutes later, and is revived, with little or no brain damage. The Brain doesn't die as quickly as we think. It just idles, kinda like a car not completely running but yet we can still listen to the radio. The dropping temperature of the child's body actually saved his life.
5.
The Brain has one hemisphere?
Correct Answer
B. False
Explanation
The brain is divided into 2 sections. The Right and Left Hemispheres.
6.
The Brain is composed of three principal divisions. The Cerebrum, Cerebellum, And Brain Stem.
Correct Answer
A. True
Explanation
The statement is true because the brain is indeed composed of three principal divisions: the cerebrum, cerebellum, and brain stem. The cerebrum is responsible for higher cognitive functions such as memory, language, and perception. The cerebellum controls coordination and balance. The brain stem connects the brain to the spinal cord and controls basic functions like breathing and heart rate. Therefore, the statement accurately describes the divisions of the brain.
7.
Which part of the brain fills up the entire upper part of your skull?
Correct Answer
C. Cerebrum
Explanation
Our cerebrum is very important when it comes to brain functions.
8.
Which part of the brain controls the Visual Center?
Correct Answer
B. Occipital Lobe
Explanation
Occipital Lobe is the visual center of the brain. It lies at the back portion of the brain.
9.
What does the bony vertebral column protect?
Correct Answer
D. Spinal Cord
Explanation
The bony vertebral column, also known as the backbone or spine, protects the spinal cord. The spinal cord is a long, thin, tubular bundle of nervous tissue that extends from the base of the brain to the lower back. It is a vital part of the central nervous system and is responsible for transmitting signals between the brain and the rest of the body. The bony vertebral column acts as a protective casing around the delicate spinal cord, shielding it from potential injuries or damage.
10.
Nerves penetrate only certain portions of the body?
Correct Answer
B. False
Explanation
Nerves penetrate EVERY part of the body!
11.
The cerebellum is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance
Correct Answer
A. True
Explanation
The statement is true because the cerebellum is indeed located under the cerebrum. The cerebellum is a part of the brain that plays a crucial role in coordinating muscle movements, maintaining posture, and balance. It receives information from various sensory systems and uses that information to regulate and fine-tune motor activities.
12.
The brainstem includes the midbrain, pons, and medulla. It acts as a relay center connecting the cerebrum and cerebellum to the spinal cord. It performs many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing. Ten of the twelve cranial nerves originate in the brainstem.
Correct Answer
A. True
Explanation
The brainstem is indeed composed of the midbrain, pons, and medulla. It serves as a crucial relay center, connecting the cerebrum and cerebellum to the spinal cord. Additionally, the brainstem is responsible for numerous automatic functions including breathing, heart rate, body temperature regulation, sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing. Furthermore, ten out of the twelve cranial nerves have their origins in the brainstem.
