Nervous System Explained In Simple Words

The video explores the nervous system, highlighting its role in maintaining body balance and communication. It explains the central and peripheral nervous systems, their subdivisions, and functions. The video also covers the types of cells in the nervous system, including neurons and glial cells, and their roles. It concludes with an explanation of neural circuits and reflex actions, emphasizing the complexity and importance of the nervous system in daily life.

What is the primary function of the nervous system?

• To communicate between body parts

• To digest food

• To produce hormones

• To circulate blood

Which part of the nervous system is responsible for voluntary movements?

• Central nervous system

• Autonomic nervous system

• Somatic nervous system

• Enteric nervous system

What does the parasympathetic nervous system primarily control?

• Fight or flight response

• Rest and digest response

• Voluntary muscle movements

• Sensory perception

What is the role of oligodendrocytes in the nervous system?

• To act as immune cells

• To sense external stimuli

• To provide insulation in the CNS

• To transmit nerve impulses

Which type of neuron carries signals from the CNS to the periphery?

• Efferent neurons

• Afferent neurons

• Interneurons

• Sensory neurons

What is the function of interneurons in a neural circuit?

• To transmit signals to muscles

• To connect afferent and efferent neurons

• To sense environmental changes

• To provide insulation to axons

In a reflex circuit, what is the role of the spinal cord?

• To transmit signals to the brain

• To process sensory information

• To directly relay signals to motor neurons

• To initiate voluntary movements
