Nervous System Quiz: Now time to test all yourself

2.

The brain is found in:

Rib cage
Skull
Hand
Abdomen

Correct Answer

A. Skull

Explanation

The brain is found in the skull. The skull is the bony structure that protects the brain and other vital organs of the head. It provides a hard, protective barrier that shields the brain from injury and trauma. The brain is a vital organ responsible for controlling and coordinating various bodily functions, including thoughts, emotions, movement, and sensory perception. Therefore, it is located within the skull to ensure its protection and proper functioning.

The _______ connects the brain to the nerves.

Heart
Muscles
Spinal cord
Food pipe

Correct Answer

A. Spinal cord

Explanation

The spinal cord is the correct answer because it is the main pathway for information to travel between the brain and the peripheral nerves. It is a long, thin, tubular bundle of nerves that extends from the base of the brain down through the spinal canal. The spinal cord plays a crucial role in transmitting sensory information from the body to the brain and motor commands from the brain to the muscles, allowing for communication and coordination between the brain and the rest of the body.

4.

The brain is divided into left and right hemispheres.

True
False

Correct Answer

A. True

Explanation

The brain is indeed divided into left and right hemispheres. This division is known as brain lateralization, and it means that each hemisphere has its own specialized functions. The left hemisphere is typically associated with language processing, analytical thinking, and logical reasoning, while the right hemisphere is more involved in creativity, spatial awareness, and emotional processing. This division allows for efficient processing and coordination of various cognitive tasks.

The key role of the nerves is to carry signals from the nervous system to the rest of the body.

True
False

Correct Answer

A. True

Explanation

Nerves play a crucial role in transmitting signals from the nervous system to the rest of the body. They act as communication pathways, allowing information to travel between the brain, spinal cord, and various organs and tissues. This enables the body to coordinate and control its functions effectively. Without nerves, the nervous system would be unable to send important signals, leading to a breakdown in communication and impaired bodily functions. Therefore, the statement that the key role of nerves is to carry signals from the nervous system to the rest of the body is true.

6.

The Nervous system is responsible for digesting the food we eat.

True
False

Correct Answer

A. False

Explanation

The statement is false because the nervous system is not responsible for digesting the food we eat. The digestive system, which includes organs like the stomach and intestines, is responsible for breaking down and absorbing nutrients from the food we eat. The nervous system, on the other hand, is responsible for transmitting signals between different parts of the body and coordinating bodily functions.

Select the right options:The central nervous system consists of-

Brain
Spinal cord
Peripheral Nerves
Heart

Correct Answer(s)

A. Brain
A. Spinal cord

Explanation

The central nervous system is responsible for coordinating and controlling the activities of the body. It consists of two main components, the brain and the spinal cord. The brain is the control center of the body, receiving and processing information from the senses and sending out signals to various parts of the body. The spinal cord is a long, tubular structure that extends from the brain and transmits signals between the brain and the rest of the body. Peripheral nerves, on the other hand, are not part of the central nervous system but rather connect the central nervous system to the limbs and organs. The heart, although an important organ, is not part of the central nervous system.

8.

The nervous system is divided into central nervous system and ____________________.

Correct Answer(s)
peripheral nervous system

Explanation
The nervous system is divided into two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord, which are responsible for processing and coordinating information. On the other hand, the PNS consists of all the nerves and ganglia outside of the CNS. It connects the CNS to the rest of the body, allowing for the transmission of sensory information from the body to the CNS, and the transmission of motor commands from the CNS to the muscles and organs. Therefore, the correct answer is the peripheral nervous system.
