Nervous System Physiology

What is the main function of the nervous system?

• To regulate body temperature

• To digest food

• To send and receive signals throughout the body

• To produce hormones

Which part of the nervous system controls voluntary movements?

• Digestive system

• Autonomic nervous system

• Endocrine system

• Somatic nervous system

What are the two main divisions of the nervous system?

• Peripheral Central System (PCS) and Nervous Central System (NCS)

• Central Nervous System (CNS) and Peripheral Nervous System (PNS)

• Brain System (BS) and Spinal System (SS)

• Sensory Nervous System (SNS) and Motor Nervous System (MNS)

What is the role of neurons in the nervous system?

• Neurons transmit electrical and chemical signals in the nervous system.

• Neurons regulate blood flow in the nervous system.

• Neurons store memories in the nervous system.

• Neurons produce hormones in the nervous system.

Explain the process of neurotransmission in the nervous system.

• Neurotransmission involves the release of neurotransmitters, their binding to receptors, and the subsequent generation of electrical signals in the receiving cell.

• Neurotransmission is the process of converting light into sound signals in the brain.

• Neurotransmission is the process of storing memories in the spinal cord.

• Neurotransmission involves the release of hormones into the bloodstream.

What is the function of the spinal cord in the nervous system?

• The spinal cord regulates blood flow in the body

• The spinal cord is responsible for producing red blood cells

• The spinal cord produces hormones for the nervous system

• The function of the spinal cord in the nervous system is to transmit nerve signals between the brain and the body, as well as coordinate reflex actions.

How does the brain communicate with the rest of the body?

• Via telepathy

• Through the circulatory system

• By sending smoke signals

• Through the nervous system

What is the fight or flight response and how does the nervous system control it?

• The fight or flight response is controlled by the central nervous system.

• The fight or flight response is controlled by the endocrine system.

• The fight or flight response is controlled by the parasympathetic nervous system.

• The fight or flight response is controlled by the autonomic nervous system, specifically the sympathetic nervous system.

Describe the role of the autonomic nervous system in regulating involuntary functions.

• The autonomic nervous system regulates voluntary functions

• The autonomic nervous system has no role in regulating involuntary functions

• The autonomic nervous system regulates involuntary functions through its sympathetic and parasympathetic branches.

• The autonomic nervous system only regulates the digestive system

What are some common disorders of the nervous system?

• Hypertension

• Diabetes

• Asthma

• Alzheimer's disease, Parkinson's disease, multiple sclerosis, epilepsy, stroke
