That was an automatic reflex.
Depends on the reflex, but a classic reflex is totally without thought. You can not suppress it even if you try.
Atrial reflex is also known as the Bainbridge reflex which is an increase in heart rate due to central venous pressure of the heart. The atrial reflex controls the heart rate more so in dogs than in humans or other primates.
"reflex"
That would be a reflex is a rapid automatic response of the body.
Reflex actions are not controlled by the brain.
Most of them are controlled by the spinal column.
A spinal reflex does not involve the brain. This type of reflex is controlled by the spinal cord and does not require the brain to initiate a response. Examples include the knee-jerk reflex and the withdrawal reflex.
Reflex responses are controlled by the spinal cord and brainstem. The spinal cord is responsible for generating motor responses to sensory input without involving the brain in order to produce quick reflex actions.
pupillary light reflex is controlled by parasympathetic branch of Autonomous nervous system
The knee-jerk reflex is controlled by the interneurons in the spinal cord.
no
The statement "The patellar knee jerk reflex is controlled by the brain" is not correct. The patellar knee jerk reflex is actually a spinal reflex, meaning it does not involve the brain in its initial response.
The pupil reflex is controlled by the autonomic nervous system, specifically the parasympathetic and sympathetic divisions. Constriction of the pupil (miosis) is controlled by the parasympathetic system through the action of the cranial nerve III (oculomotor nerve). Dilation of the pupil (mydriasis) is controlled by the sympathetic system through the action of the superior cervical ganglion.
a reflex ia an example of an instinctive response
The Achilles reflex is also known as the ankle-jerk reflex. it is controlled by the S1 segment of the spinal chord and occurs when the Achilles tendon is struck with a rubber hammer.
The medial rectus muscles are primarily responsible for the convergence reflex. When focusing on a near object, these muscles contract to rotate both eyes inward, allowing them to converge and maintain single binocular vision.
