Nervous System

HideShow resource information
An Effector...
Is either a muscle or a gland.
1 of 13
A Reflex...
Fast, automatic responses to certain stimuli.
2 of 13
A Motor Neurone...
Nerve cells that carry electrical impulses from the relay neurones in the CNS (Central Nervous System) to the effectors.
3 of 13
A Receptor...
Many of these are found in our sense organs. They detect the stimulus.
4 of 13
A Relay Neurone...
Nerve cells that carry electrical impulses from sensory neurones to motor neurones. They are found in the CNS (Central Nervous System).
5 of 13
A Stimulus...
A change in your environment.
6 of 13
A Reflex Arc...
Different to a normal nervous pathway as the brain is no co-ordinating the response.
7 of 13
CNS...
Central Nervous System. Brain and spinal cord co-ordinates the response.
8 of 13
A Sensory Neurone...
Nerve cells that carry electrical impluses from the receptor cells in the sense organs to the relay neurones in the CNS (Central Nervous Symstem).
9 of 13
Sense Organs...
Certain receptor cells to detect stimuli. These receptor cells consist of a nucleus, cytoplasm and cell membrane.
10 of 13
A Synapse...
A gap between two neurones, it contimnues the message via chemicals being released, and diffusing across the gap.
11 of 13
A Gland...
An effector that responds by secreting chemicals calls hormones.
12 of 13
A Muscle...
An effector that responds by contracting.
