Nervous System

Question 1

What is nervous system?

Answer 1

Detects changes and coordinates responses

Question 2

Where is Central Nervous System?

Answer 2

Brain and spinal cord.

Question 3

Where is peripheral nervous system?

Answer 3

nerve works

Question 4

How do Nervous System Response.

Answer 4

Stimulus: changes in the surrounding → Receptor:sensory cells that detects stimulus → Processing centre: CNS → Effector: Muscle/Gland → Response.

Question 11

What is Sensory Neurone?

Answer 11

Transmit impulses from the sensory cell to CNS. Long dendron and short axon.

Question 12

What is Motor Neurone?

Answer 12

Transmit impulses from CNS to effector. Long axon
