Nerve Functions and Types

The video tutorial explains the pathways from stimulus to response in living organisms, focusing on the role of nerves. It classifies nerves into three types: sensory (afferent), motor (efferent), and association (mixed) nerves. Sensory nerves receive information from body parts and send it to the brain, while motor nerves transmit responses from the brain to body parts. Association nerves, located in the spinal cord, handle reflex actions and immediate responses. The tutorial highlights the importance of these nerves in processing and responding to environmental stimuli.

What is the primary role of nerves in living organisms?

• To store nutrients

• To protect organs

• To produce energy

• To transmit information

Which type of nerve is responsible for receiving information from body parts?

• Motor nerves

• Sensory nerves

• Central nerves

• Association nerves

What is the function of the nucleus in a sensory nerve?

• To receive stimuli

• To push to one side

• To store information

• To transmit signals

Motor nerves are also known as:

• Central nerves

• Afferent nerves

• Mixed nerves

• Efferent nerves

In which direction do motor nerves send responses?

• From body parts to brain

• From brain to body parts

• Within the spinal cord

• From one nerve to another

What is the primary function of association nerves?

• To store energy

• To coordinate immediate responses

• To transmit sensory information

• To protect the spinal cord

Where are association nerves primarily located?

• In the heart

• In the spinal cord

• In the brain

• In the muscles

Which type of nerve is involved in both receiving and sending information?

• Peripheral nerves

• Association nerves

• Sensory nerves

• Motor nerves

What role does the spinal cord play in neural pathways?

• It produces hormones

• It protects the brain

• It manages certain functions

• It stores nutrients

How do sensory and motor nerves interact in response to stimuli?

• Motor nerves receive stimuli from the environment

• Sensory nerves send responses to the brain

• Sensory nerves receive stimuli and motor nerves send responses

• Both types of nerves perform the same function
