What neurotransmitter neuron to muscle cell?
sensory neurones
Three differences between sensory neurone and motor neurone?
# Motor neurones have cell bodies inside the Central Nervous System (CNS) whilst in sensory neurones the cell body is located outside of the CNS # Motor neurones transmit impulses from the CNS to the effector which brings about a response to the situation, sensory neurones transmit impulses from to the CNS from the receptor. # Sensory neurones transmit impulses as a result of external stimuli such as pressure, light, temperature etc. Motor neurone transmit impulses passed along the CNS to the effector.
What reflex has at least one interneuron placed between the sensory and motor neurons?
Polysynaptic Reflex
What is the connection between sensory nerves and the neurons in the brain?
Sensory nerves transmit information from sensory receptors in the body to the neurons in the brain. When sensory receptors detect stimuli such as touch, temperature, or pain, they send signals through sensory nerves to the brain. Neurons in the brain then process and interpret these signals, allowing us to perceive and respond to the sensory information.
Why do the sensory neuron has short axon and long dendrites?
sensory and motor neurons are sometimes very long so that the impulses can be carried away from the body very quickly. in the motor neuron the impulses "jump" over the fatty tissue to the Node Of Ranvier.
Type of neurones along a reflex arc?
the sensory receptor begins then the Relay neuron and final the motor neuron
Why does the body have both sensory and motor neurones?
the body has both sensory and motor neurones because the sensory neurones sense what is happening and sends the message along and like a motor the motor neurones pass on the message constantly round and round until it reaches its destination
Similarities of motor and sensory neurons?
Sensory neurones carry impulses to the CNS, motor neurones carry impulses to muscles.
What type of neuron's involved in a knee jerk?
sensory neurones motor neurones
What neurotransmitter neuron to muscle cell?
sensory neurones
How many synapses occur in this reflex arc?
there are 2 - one between the sensory and relay neurones; the other between the relay and motor neurones.
A reflex arc begins with the stimulation of a what?
A reflex arc begins with the stimulation of a sensory receptor such as those on the skin. The stimulus is then passed as an electrical impulse along sensory, relay and motor neurones (by-passing the brain) before reaching an effector orgen, like a muscle, which then responds to the stimulus.
The sensory receptor sensory neuron motor neuron and effector involved in a reflex form a?
A reflex arc.
A knee-jerk reflex employs motor neurons and what?
it employs sensory and motor neurons
What reflex does a a sensory neuron synapses directly on a motor neuron?
Monosynaptic reflex
Three differences between sensory neurone and motor neurone?
# Motor neurones have cell bodies inside the Central Nervous System (CNS) whilst in sensory neurones the cell body is located outside of the CNS # Motor neurones transmit impulses from the CNS to the effector which brings about a response to the situation, sensory neurones transmit impulses from to the CNS from the receptor. # Sensory neurones transmit impulses as a result of external stimuli such as pressure, light, temperature etc. Motor neurone transmit impulses passed along the CNS to the effector.
How does the human reflex system work?
Reflex actions involve just three types of neurone. These are : - sensory neurones, - motor neurones, and Relay neurones which simply connect a sensory neurone and a motor neurone. We find relay neurones in the CNS, often in spinal cord
