Nervous System - Recap

What are neurones?

What neurone is this?

• Sensory neurone

• Motor neurone

• Relay neurone

What neurone is this?

• Sensory neurone

• Motor neurone

What is the function of a relay neurone?

• Transmits nerve impulses from receptors to the central nervous system

• Transmits nerve impulses within the central nervous system

• Transmits nerve impulses from the central nervous system to the effectors

A reflex action is an immediate response to a specific stimulus with conscious control.

• True
• False

Organise the nervous pathway in a reflex arc:

• Sensory Neurone

• Receptor

• Motor Neurone

• Relay Neurone

• Effector

Organize these options into the right categories

Groups:

(a) Endocrine control

,

(b) Nervous control

• quick responses

• Always Involuntary

• Short or long-lived responses

• usually 1 target area (localised)

• short-lived responses

• May affect more than 1 target organ

• neurones transmit nerve impulses

• blood as transport medium

• Hormone as signals

• Nerve impulses as signals

• slow responses

• may be voluntary or involuntary
