What are the two functional classifications of reflexes?
The two functional classifications of reflexes are autonomic reflexes, which regulate activities of smooth muscle, cardiac muscle, and glands, and somatic reflexes, which involve skeletal muscles. Autonomic reflexes are involuntary and controlled by the autonomic nervous system, while somatic reflexes are voluntary and controlled by the somatic nervous system.
What controls pupilary and auditory reflexes?
Pupillary reflexes are controlled by the autonomic nervous system, specifically the parasympathetic and sympathetic divisions. Auditory reflexes are controlled by the brainstem, which receives and processes auditory information from the ears via the auditory nerve.
What type of reflexes are not subject to conscious control?
Involuntary reflexes, such as the knee-jerk reflex or pupillary reflex, are not subject to conscious control. These automatic responses are typically controlled by the spinal cord or brainstem without involvement of higher brain regions.
Can a person be unconscious yet still have involuntary reflexes such as coughing or facial movements?
Yes, it is possible for a person to be unconscious and still exhibit involuntary reflexes such as coughing or facial movements. These reflexes are controlled by the autonomic nervous system and do not require conscious input from the brain.
Can you think of an action where your brain is not involved?
All simple reflexes. The chemistry of your gut and liver. (digestion)
What structure controls simple reflexes?
Reflex responses are controlled in your spinal chord, not in your brain (;- your welcome

What is controlled by the spinal cord?
The whole body. The spinal cord acts as the transmission system that transmits nervous signals from the brain to the rest of our body. Also, the spinal cord controls numerous nervous reflexes in our body. It is about 45 cm long for men and 43 cm long for women.
What an example of a reflex action?
One example of a reflex is when your leg jerks after a doctor hits it with a hammer.-------------------------------------------A reflex action is a sudden reaction to a stimuli (a change in the environment) & often acts to protect you.Some are controlled by the brain (cranial reflexes) such as when you blink as dust lands in your eye, or your pupil gets smaller as light is shone in your eye.Some reflexes are controlled by the spinal cord (spinal reflexes) such as when you touch a hot object or stand on a pin.Some reflexes can have learnt responses so they are called conditioned reflexes. These reflexes occur without you even thinking about them e.g. walking & producing saliva when you smell food.
What type of reflexes are not subject to conscious control?
Involuntary reflexes, such as the knee-jerk reflex or pupillary reflex, are not subject to conscious control. These automatic responses are typically controlled by the spinal cord or brainstem without involvement of higher brain regions.
What part of the brain controls simple reflexes that do not involve the brain?
spinal cord
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.
Can a person be unconscious yet still have involuntary reflexes such as coughing or facial movements?
Yes, it is possible for a person to be unconscious and still exhibit involuntary reflexes such as coughing or facial movements. These reflexes are controlled by the autonomic nervous system and do not require conscious input from the brain.

What are facts about reflex?
Reflexes are automatic responses to stimuli that help protect the body from harm. They occur rapidly, without conscious thought or awareness. Reflexes are controlled by the spinal cord and do not involve the brain in the decision-making process.
CAN reflex action controlled by spinal cord?
Simple reflexes are controlled by the spinal cord. The message travels from the sense receptors near the skin through the afferent nerve fibers to the spinal cord. In the spinal cord, the messages are relayed through association neurons to the efferent nerve fibers, which carry them to the muscle cells that cause the reflex movement.
