What part of the body is not a reflex action in humans?
Conscious actions, such as voluntary movements controlled by the brain, are not reflex actions in humans. These actions involve decision-making and higher brain functions, unlike reflex actions which are automatic responses to stimuli.
What nerve acts as the afferent pathway in the pupillary reflex?
The optic nerve (cranial nerve II) carries sensory information about light intensity to the brain as part of the afferent pathway in the pupillary reflex.
Is salivation an automatic reflex?
The withdrawal reflex is both a somatic and autonomic reflex (brain). Withdrawal from a painful stimulus is one test used in brain injury. Without the somatic connection to the autonomic brain areas, you'd have no withdrawal reflex at all when something interferes with that connection (such as brain injury or brain death).
What part of brain controls pupil dilation?
Edinger-Westphal nucleus of the brainstem controls the pupil reflex. An ER doctor who looks at the response to a pen light is checking on brain stem activity.
Why brain is not involve during reflex actions?
A reflex action or reflex arc bypasses the brain as to decrease transmission time from detection to response, i.e. the time it takes for the body to initiate a response in relation to the effecting stimulus. This decrease in time allows for minimal damage to tissue or surrounding cells which may be affected by a certain stimulus.
Can part of the impulse in a reflex action reach the brain?
because it is the cells
What part of the body is not a reflex action in humans?

What part of the nervous system is not involved in producing reflex actions?
The cerebral cortex is not directly involved in producing reflex actions. Reflex actions are controlled at the spinal cord or lower levels of the brain without involvement of higher brain centers like the cerebral cortex.
What nerve acts as the afferent pathway in the pupillary reflex?
The optic nerve (cranial nerve II) carries sensory information about light intensity to the brain as part of the afferent pathway in the pupillary reflex.
Why is the patellar reflex called a somatic reflex?
The Patellar reflex is an example of a somatic reflex. This refers to the branch of the nervous system that the reflex pertains to. The somatic branch is part of the Peripheral Nervous system, meaning that it's reflex arc does not pass through the central nervous system (the spinal cord and the brain)
What is the difference between a reflex arc and a normal nerve impulse?
A reflex arc doesn't go all the way up to the brain. Thus it NEVER becomes part of the thought process.
What is the part in reflex in the response?
Reflex action is your body's reflex against injury. It is needed in every part of your body.
Is salivation an automatic reflex?
The withdrawal reflex is both a somatic and autonomic reflex (brain). Withdrawal from a painful stimulus is one test used in brain injury. Without the somatic connection to the autonomic brain areas, you'd have no withdrawal reflex at all when something interferes with that connection (such as brain injury or brain death).
What Part of the brain responsible for licking and eating reflexes?
The part of the brain responsible for eating are appetite centers of the amygdala and hypothalamus. The licking reflex is seen only certain animals but the centers are located in the medulla oblongata in the lower brainstem.
What part of brain controls pupil dilation?
Edinger-Westphal nucleus of the brainstem controls the pupil reflex. An ER doctor who looks at the response to a pen light is checking on brain stem activity.
Which portion of the human brain mediates simple reflexes such as sneezing coughing and salivating?
The medulla oblongata is a part of the brain stem involved in these reflexes. And no your eyes will not pop out if you sneeze with them open. Closing the eyes is part of the reflex and you have no control over reflexes.
What part of the brain is responsible for eating and licking reflexes?
The brainstem, specifically the medulla oblongata, is responsible for controlling eating and licking reflexes. This region helps coordinate the reflex actions involved in chewing, swallowing, and licking.
