What else can I help you with?
Where does the nerve impulse travel from the reflex arc?
The nerve impulse typically travels from the sensory neuron to the spinal cord, where it is processed by interneurons, and then to the motor neuron to elicit a response from the effector organ or muscle.
What does the axial do?
Carry a nerve impulse to the next nerve OR to an effector cell.
What does the axial filament do?
Carry a nerve impulse to the next nerve OR to an effector cell.
What is an effector cell?
The effector cell responds to a nerve impulse and can be either a muscle cell or a gland cell.
The neurotransmitters of a neutron enable a nerve impulse to do what?
Neurotransmitters in a neuron allow a nerve impulse to be transmitted from one neuron to another by crossing the synapse and binding to receptors on the receiving neuron. This triggers an electrical or chemical signal to continue the nerve impulse along the neural pathway.
What begins when a neuron is stimulate by another neuron in its environment?
A nerve impulse
First step in a reflex arc?
A reflex arc involves the following components:The receptor is the part of the neuron (usually a dendrite) that detects a stimulus.The sensory neuron transmits the impulse to the spinal cord.The integration center involves one synapse (monosynaptic reflex arc) or two or more synapses (polysynaptic reflex arc) in the gray matter of the spinal cord.A motor neuron transmits a nerve impulse from the spinal cord to a peripheral region.An effector is a muscle or gland that receives the impulse from the motor neuron. In somatic reflexes, the effector is skeletal muscle. In autonomic (visceral) reflexes, the effector is smooth or cardiac muscle, or a gland.
What is the order of impulse conduction thru reflex arc?
A reflex is an automatic response, that protects the organism from a harmful stimulus. The receptors detect a stimulus which generates a nerve impulse along the sensory neurone to the Central Nervous System (CNS). The CNS decides the appropiate response to the stimulus. The nerve impulse then travels across a synapse to the relay neurone, across another synapse to the motor neurone to the effector. This is normally a muscle or an organ which moves or responds to bring about a response appropiate to the stimulus.
What carries a nerve impulse from one neuron to annother?
Neurotransmitter.
What is a neuron that transmits a nerve impulse toward the central nervous system is called what?
A sensory neuron transmits a nerve impulse towards the central nervous system. These nerve cells activated by input, transmits sensory information.
Where does a nerve impulse start?
A nerve impulse typically starts at the dendrites of a neuron, where it receives signals from other neurons or sensory receptors. These signals are then transmitted down the axon of the neuron to the axon terminals, where they can communicate with other neurons or target cells.
What is the route followed by nerve impulses when one neuron communicates with another?
When one neuron communicates with another, the nerve impulse travels down the axon of the presynaptic neuron, reaches the axon terminal, triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron's dendrites, initiating a new nerve impulse in the postsynaptic neuron.
