1
Q

Nervous System Response Chain

A

Receptor - Sensory Neurone - Coordinator (CNS) - Motor Neurone - Effector

2
Q

Reflex Pathway

A

Bypasses the CNS Stimulus - Receptor - Sensory Neurone - Relay Neurone - Motor Neurone - Effector - Response

3
Q

Neurones

A

Basic cells of the nervous system that carry minute electrical IMPULSES (not messages) around the body

4
Q

Nerves

A

Bundles of hundreds/thousands of Neurones

5
Q

CNS

A

The Central Nervous System is made up of the brain and spinal cord where information is processed.

6
Q

Sensory Neurones

A

Neurone which carries impulses from the sensory organs to the CNS

7
Q

Motor Neurones

A

Neurone that carries impulses from the CNS to the effector organs.

8
Q

Relay Neurones

A

Reflex Actions. Connect the Sensory Neurone to the Motor Nerone. Found in the CNS.

9
Q

Synapse

A

A gap between neurones where the transmission of information is chemical not electrical.

10
Q

How a synapse works

A
  1. Impulse arrives in neurone 2. Sacs containing chemicals release them into he gap between the neurones. 3. Chemicals attach themselves to the surface of the next neurone and set up a new electrical impulse.
11
Q

Cerebral Cortex

A

Consciousness, Intelligence, memory, language + thought.

12
Q

Cerebellum

A

Movement + Balance

13
Q

Medulla

A

Unconscious Activity

14
Q

Hypothalamus

A

Regulation of body functions

15
Q

Pituitary Gland

A

Produces hormones
