The Nervous System Crash Course Part 1

What are the two main parts of the nervous system?

• Central and Peripheral Nervous Systems

• Brain and Spinal Cord

• Somatic and Autonomic Nervous Systems

• Sympathetic and Parasympathetic Nervous Systems

What does the central nervous system consist of?

• Brain and Spinal Cord

• Brain and Nerves

• Spinal Cord and Nerves

• Neurons and Glial Cells

What is the role of the peripheral nervous system?

• To produce myelin sheath

• To communicate between the central nervous system and the rest of the body

• To process information

• To control voluntary movements

What are neurons?

• Cells that respond to stimuli and transmit signals

• Cells that make up the majority of the brain

• Cells that produce myelin

• Cells that support and protect neurons

What are glial cells?

• Cells that are found only in the peripheral nervous system

• Cells that support and protect neurons

• Cells that transmit electrical impulses

• The main immune defense in the brain

What is the function of the autonomic nervous system?

• It controls voluntary muscle movements

• It processes sensory information

• It is responsible for the fight or flight response only

• It controls involuntary functions like heartbeat and digestion

What are the three principal functions of the nervous system?

• Sleep, wakefulness, and reflex actions

• Breathing, digestion, and circulation

• Cognitive function, emotional response, and memory

• Sensory input, integration, and motor output

What is the role of sensory neurons?

• To transmit impulses from sensory receptors to the CNS

• To support and protect neurons

• To transmit impulses from the CNS to muscles

• To connect different neurons within the CNS

What is the myelin sheath?

• A part of the central nervous system

• An insulating layer around the axon

• A sensory receptor

• A type of neuron

What happens when the nervous system gets damaged?

• It affects the body's ability to process and respond to information

• It can regenerate completely

• It increases the efficiency of the nervous system

• It has no significant effect
