The two are different because of what triggers the reflex. While the patella is triggered through the sense of touch, the pupillary is triggered through light.
differentiate between a dynamic stretch reflex and a static stretch reflex
Sharks have no gag reflex.
There are two long bones in the stifle joint. The stifle joint is made up of the femur, tibia and patella. The femur and tibia are long bones, and the patella is a sesamoid.
Yes, and when they walk they go wee wee all the way home like u shold be doing or else u r going to have the altomit weggie
A sesamoid is a small bone embedded within a tendon or muscle, typically found where tendons pass over joints. They help to reduce friction and provide leverage for muscles, aiding in movement. The patella (kneecap) is the largest sesamoid bone in the body.
The receptor in the pupillary reflex is the optic nerve, which senses changes in light intensity. The effector is the circular and radial muscles of the iris, which control the size of the pupil. In the pupillary reflex, both the receptor and the effector work together to adjust the size of the pupil to regulate the amount of light entering the eye.
pupillary light reflex is controlled by parasympathetic branch of Autonomous nervous system
The ciliospinal reflex and the pupillary light reflex are classified as autonomic reflexes.
Yes, the pupillary light reflex is mediated by both autonomic and somatic nervous systems. The autonomic nervous system controls the constriction of the pupil in response to light, while the somatic nervous system controls the movement of the muscles that dilate and constrict the pupil.
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.
While pupillary size in principle is controlled both by the sympathetic and the parasympathic nervous system, the typical closure of the pupil after illumination (i.e. the pupillary light reflex) is mediated by the parasympathetic innervation of the constrictor muscle of the pupil.
The most well-known human reflex is the knee-jerk (or patella) reflex. This is the one where you use a reflex hammer to hit the tendon just below the kneecap (or patella). The leg jerks out like you're kicking.
In the experiment on the photopupillary reflex, when light is shone into one eye causing pupillary constriction (direct response), the nonilluminated eye will also exhibit pupillary constriction (consensual response) due to neural connections between both eyes and the brain. This demonstrates the consensual response component of the pupillary light reflex.
The pupillary light reflex is a polysynaptic reflex. When light is sensed by the retina, a signal is sent via the optic nerve to the pretectal nuclei in the midbrain, which then sends signals to both the parasympathetic and sympathetic pathways controlling the muscles of the iris to constrict or dilate the pupil appropriately.
The pupillary reflex helps to regulate the amount of light entering the eye, allowing for optimal vision in changing light conditions. This reflex helps protect the retina from damage due to excessive light exposure and ensures that visual information is processed effectively by the brain.
You probably mean the pupillary reflex. It is the reflex responsible for your pupils constricting (becoming smaller) when exposed to light and dilating (becoming bigger) when you walk into a dark room.
The division of autonomic nervous system responsible for pupillary light reflex is the parasympathetic system. This is what causes the pupils to close down or open up in response to lighting conditions.
