The purpose is to prevent injury. For example, if someone shines a bright light in your eyes, your pupils automatically get smaller so that less light gets into the eye- this stops it getting damaged. Or if you get a shock, your body releases the hormone called ADRENALINE automastically- it dos'nt wait for a response.
Reflex behaviors in infants serve to protect and support their early development. These reflexes are instinctual reactions to stimuli, such as sucking when something touches the baby's lips. As the infant's nervous system matures, reflex behaviors gradually disappear and are replaced by intentional movements controlled by the brain.
Hormones have nothing to do in reflex arc.
corneal reflex. It involves touching the cornea with a wisp of cotton, which should trigger a blinking response mediated by the trigeminal nerve, specifically the ophthalmic branch. This reflex assesses the sensory function of the trigeminal nerve in detecting sensations on the cornea.
The occulocephalic reflex, also known as the doll's eye reflex, tests the brainstem's function by observing the eye movements in response to turning the head. In a healthy individual, the eyes should move in the opposite direction of the head turn. This reflex is utilized to assess brainstem integrity in comatose patients.
The habenular nucleus is involved in the regulation of various behaviors, including mood, reward processing, and stress responses. It also plays a role in functions such as sleep-wake cycles, learning, and memory. Dysfunction of the habenular nucleus has been implicated in conditions such as depression and addiction.

The most immediate and direct function of the rooting reflex is to help infants find the nipple when feeding. This reflex is important for ensuring that newborns can effectively nurse and receive nourishment.
The instrument used by a doctor to test knee reflex is a reflex hammer. The doctor will tap the patellar tendon just below the kneecap with the reflex hammer to elicit a reflex response, which helps assess the function of the nerves and spinal cord.
When a reflex occurs in response to a specific stimulus, the brain can reinforce associated voluntary behaviors that follow the reflex. Through repetition and reinforcement, the brain can learn to anticipate and control the reflex response, turning it into a voluntary learned behavior. This process involves the formation of new neural pathways and connections that link the reflex with the voluntary behavior.
Reflex behaviors are involuntary responses to stimuli and cannot be taught in the traditional sense. However, some behaviors that resemble reflexes, such as conditioned responses, can be trained through repetitive practice and reinforcement. This may create an automatic response to a specific stimulus over time.
Behaviors triggered by a reflex. Examples of this include sneezing after inhaling dust or the knee-jerk reaction when a doctor hammers your knee.
corneal reflex. It involves touching the cornea with a wisp of cotton, which should trigger a blinking response mediated by the trigeminal nerve, specifically the ophthalmic branch. This reflex assesses the sensory function of the trigeminal nerve in detecting sensations on the cornea.
Controls reflex of turning eyes and head towards a visual stimulus.
You can have and you have the reflex arc situated spinal cord level. The function of the reflex arc can not be overemphasized. This reflex withdrawal from the harmful stimulus protects you to great extent. Secondly the spinal cord is well placed away from the brain. So that the arrangement of nerves in your brain becomes less complicated.
The preyer reflex is a protective mechanism observed in prey animals where they exhibit defensive behaviors, such as freezing or playing dead, in response to a perceived threat or predator. This reflex aims to reduce the likelihood of being detected or attacked by the predator.
"Learned behaviors" are simply behaviors that you must learn instead of behaviors that happen automatically.Instinct and reflex are examples of behaviors which do not have to be learned - birds instinctively know how to build nests, you blink your eyes by reflex (most of the time), and hitting your knee with a little hammer makes your leg jerk.Anything that you have to practice in order to learn it is a learned behavior - walking, talking, playing sports, school work, etc.
