Nervous System Multiple Choice Questions And Answers Pdf

The nervous system is responsible for controlling and coordinating all the body's activities. It is composed of the brain, spinal cord, and nerves. The nervous system is divided into two parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS consists of all the nerves outside the CNS. This article will provide you with a comprehensive list of multiple-choice questions and answers regarding the nervous system.

What is the Nervous System?

The nervous system is the body's electrical wiring. It is responsible for sending, receiving, and processing nerve impulses to and from the brain and other parts of the body. The nervous system is responsible for coordinating all the body's activities, such as movement, sensation, and thought.

How does the Nervous System Function?

The nervous system consists of neurons that communicate with each other by sending electrical and chemical signals. These signals are transmitted via the synapses, which are the junctions between two neurons. The nervous system also consists of glial cells, which support and protect neurons.

What are the Major Structures of the Nervous System?

The major structures of the nervous system are the brain, spinal cord, and nerves. The brain is responsible for controlling all the body's activities, such as movement, sensation, and thought. The spinal cord is responsible for transmitting signals between the brain and the rest of the body. The nerves are responsible for transmitting signals to and from the brain and other parts of the body.

What are the Types of Nerves in the Nervous System?

The PNS consists of three types of nerves: sensory nerves, motor nerves, and mixed nerves. Sensory nerves are responsible for transmitting information from the senses to the brain. Motor nerves are responsible for transmitting information from the brain to the muscles. Mixed nerves are responsible for transmitting both sensory and motor information.

What are the Functions of the Different Parts of the Brain?

The brain is responsible for controlling all the body's activities. The different parts of the brain have different functions. The frontal lobe is responsible for controlling movement, speech, and decision making. The parietal lobe is responsible for processing sensory information, such as touch and taste. The occipital lobe is responsible for processing visual information. The temporal lobe is responsible for processing auditory information and memory. The cerebellum is responsible for coordinating movement and balance. The brainstem is responsible for controlling the autonomic functions, such as breathing and heart rate.

What are the Common Nervous System Disorders?

The nervous system can be affected by a variety of disorders, such as Alzheimer's disease, Parkinson's disease, epilepsy, multiple sclerosis, and neuropathy. Alzheimer's disease is a progressive disorder that affects memory and cognitive function. Parkinson's disease is a degenerative disorder that affects movement. Epilepsy is a disorder that causes seizures. Multiple sclerosis is a disorder that affects the myelin sheath that protects the nerves. Neuropathy is a disorder that affects the nerves and can cause pain, tingling, and numbness.

Conclusion

The nervous system is responsible for controlling and coordinating all the body's activities. It is composed of the brain, spinal cord, and nerves. The nervous system is divided into two parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS consists of all the nerves outside the CNS. Understanding the nervous system and its functions is crucial to maintaining good health.
