Coordination and Response Flashcards
Impulse Transmission
There are 2 Central Nervous Systems. Which are…
Brain and spinal cord
Central Nervous System
Stimuli - receptor (senses) - CNS - effector (muscle) - response
Receptors and effectors
Receptor cells when exposed to a stimulus sends an electrical impulse to the CNS
Found in sense organs (skin, nose, ears, tounge and eyes)
Neurones are
Cells in the nervous system
Types of Neurones
Sensory Neurone, Motor Neurone, Relay Neurone
Sensory Neurones…
Send info/signals or impulse to CNS
Sensory Neurones cell body is located in
The spinal nerve in between axon and axon terminal
Motor Neurones…
Deliver information from CNS to effector
Motor Neurones cell body is located in
The spinal cord in between dendrite and long axon
Relay Neurones…
Apart of CNS
Relay Neurones Cell body is located in
The spinal cord between dendrite and short axon
The Neurone Pathway is
Stimuli - Receptor (senses) - Sensory neurone - Relay neurones - Motor neurone - Effector (muscle) - Response
There are 2 Types of Movements which are
Conscious/Voluntary and Unconscious/Involuntary
Conscious/Voluntary Movement is
Having a Thinking Process (Daily Activity)
Ex. Taking a Book
Stimuli - receptors - sensory - brain - motor - effector - response
Unconscious/Involuntary Movement is
Doesn’t involve a Thinking Process (Survival)
Ex. Breathing
Stimuli - receptor - sensory - spinal cord - motor - effector - response
