What movement would you expect to occur during the Achilles reflex?
The Achilles reflex is also known as the ankle jerk reflex. If the Achilles tendon is tapped, the foot should jerk towards its plantar surface.
What extrinsic eye muscles are controlled during the convergence reflex?
The voluntary muscles of the eye is the extrinsic eye muscle that are controlled during the convergence reflex. The convergence reflex is keen on keeping the eye alert.
What is the function of reflex arc?
The reflex arc allows sensory neurons to synapse in the spinal cord instead of the brain, allowing actions to occur relatively quickly by activating spinal motor neurons without needing to send signals through the brain. For example, a person touching a hot stove would flinch before thinking about it, and protect tissues from further damage.
Is the knee-jerk reflex a simple reflex stretch reflex or a spinal reflex?
spinal reflex
What two cranial nerves on the stimulated side must be functional for pupillary light reflex to occur?
Cranial nerves 2 and 3
What movement would you expect to occur during the Achilles reflex?
The Achilles reflex is also known as the ankle jerk reflex. If the Achilles tendon is tapped, the foot should jerk towards its plantar surface.
Why do you get goose bumpes?
Goose bumps, or the pilomotor reflex, is caused by tiny muscles contracting at the base of each hair on the skin. It can occur when cold but also during strong emotion.
What reflex action occur when you are hungry and smell cooking food?
your stomach grumbles
How many synapses are crossed in a single reflex arc during a muscle stretch reflex?
one
What extrinsic eye muscles are controlled during the convergence reflex?
The voluntary muscles of the eye is the extrinsic eye muscle that are controlled during the convergence reflex. The convergence reflex is keen on keeping the eye alert.
How does the mechanoreceptor reflex effect breathing?
The mechanoreceptor reflex is composed of the inflation reflex and the deflation reflex. The inflation reflex limits the duration of inspiration in response to stretching the walls of the lungs. The deflation reflex stimulates inspiration when the lungs are collapsed. Mechanoreceptor reflexes are insignificant during quiet respiration but they are very important during forced respiration. The mechanoreceptor reflex makes sure your brain knows when to stop breathing and start breathing, basically.
During a reflex the nerve impulse reaches?
the brain
What is a somatic reflex and how does it occur through the CNS?
A somatic reflex is where the body responds to stimulus. The message from the stimulus is sent through the central nervous system via the spine, and from there it travels to the brain.
Why don't we have to think before a reflex?
Because reflexes only occur at the level of the spinal cord, not the brain.
During a knee-jerk reflex the nerve impulse is received by the?
The knee-jerk reflex is controlled by the interneurons in the spinal cord.
Why does moro reflex occur in children?
Actual reason is unknown, but conjecture is that it is an attempt to grab its mother as it begins to fall.
What is the importance of reflex actions?
One important aspect of reflex action is to help protect us without having to think. Reflex actions are involuntary and quick. They are done to meet an emergency and occur at the level of the spinal cord. Examples include the gag reflex clearing unplanned foreign objects or your eyelid closing when something gets near your eye.
