What occurs during the reflex arc.?
The pathway that an impulse travels from your foot back to your leg is an example of a reflex arc. A reflex arc includes a sensory receptor (in this case, a receptor in your toe), sensory neuron, motor neuron, and effector (leg muscle). Some reflex arcs include interneurons. In other reflex arcs, a sensory neuron communicates directly with a motor neuron.
How does the brain send and receive messages from our body?
The brain receive messages from the other parts of the body through nerve impulses.
Structure that carries messages between the brain snd other parts of the body?
The Neuron, and in this case, a motor neuron or a sensory neuron.
What does it mean if you have no reflex in one arm?
It can be a indicator of some other medical conditions. Like, myopathy, neuropathy, spondylosis, sensory nerve disease, neuritis, or a potential lower motor neurone lesion.
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.
Which tissue carries messages from your brain and spinal cord to other parts of your body?
The answer is motor part of the peripheral nervous system. It has got another part called as sensory nervous system, which carry message towards central nervous system.
The part of the neuron that is responsible for receiving information signals from other neurons is called?
Dendrites are the part of a neuron which receives chemical messages (neurotransmitters) through synapses.Mostly the dendrites receive messages from other neurons, but the cell bodies of neurons also receive direct synaptic inputs from other cells.
What is motor nervous?
You are probably thinking of motor nerves. Those are the nerves which transmit messages from the brain to the muscles, causing movement. The other kind of nerves are sensory, which transmit sense perceptions.
How is a reflex nerve impulse different than other nerve impulses?
Skeletal muscles interact with the spinal cord
What is a GI reflex pathway?
Many neurons of the ENS re components of GI reflex pathways that regulate GI secretion and mobility in response to stimuli present in the lumen of the GI tract 1. sensory receptors (such chemoreceptors nd stretch receptors) 2. the axons of the sensory neurons can synapse with other neurons located in the ENS, CNS, OR ANS 3. the neuons of the ENS, CNS, or ANS subsequently activate or inhibit GI glads and smooth muscles, altering GI secretion and motility
How are olfactory neurons classified structurally?
Neurons are classified by the direction they move.
What 3 neurons make up a reflex arc?
There are actual two types of reflex arc. One contains just two and the other contains three.A reflex arc involves the following components:1. The receptor (sensory neuron) that detects a stimulus.The sensory neuron transmits the impulse to the spinal cord.2.The integration center (interneuron) in the cord. This one can be missing. If it is, the reflex is very, very rapid. If the interneuron is used, it can send information up the cord to the brain. Your response will be faster than your brain's "knowing" what happened.3. 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 form 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.
