Oculocardiac reflex can be profound during eye examination for retinopathy of prematurity. [5] However, this reflex may also occur with adults. Bradycardia, junctional rhythm and asystole, all of which may be life-threatening, [6] can be induced through this reflex. This reflex has been seen to occur during many pan facial trauma surgeries due ...
The skull bone behind Hermansen’s right eye was gone. In its place was a hole, allowing her brain to press against the eye, which explained the pulsating, said Dr. Netanel Ben-Shalom, a ...
Notably, hippos in antiquity referred to involuntary eye movements which are nowadays called nystagmus. [4] It is particularly noticeable when pupil function is tested with a light, [2] but is independent of eye movements or changes in illumination. [1] It is usually normal, however pathological hippus can occur. [2] [3]
Blood squirt (blood spurt, blood spray, blood gush, or blood jet) is a projectile expulsion of blood when an artery is ruptured. Blood pressure causes the blood to bleed out at a rapid, intermittent rate in a spray or jet, coinciding with the pulse, rather than the slower, but steady flow of venous bleeding.
In humans, the movements of oculomotor muscles ("eye-blink reflex" or "eye-blink response" assessed using electromyographic recording of orbicularis oculi muscle and by oculography) could be used as a measure. Pulse-alone results are compared to prepulse-plus-pulse, and the percentage of the reduction in the startle reflex represents prepulse ...
In medicine, the pulse is the rhythmic throbbing of each artery in response to the cardiac cycle (heartbeat). [1] The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery or ulnar artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint ...
He proposed that the brain housed the intellect rather than the heart. He was the first person to differentiate between the cerebrum and the cerebellum, and to place individual importance on each portion. He looked more in depth into the network of nerves located in the cranium. Herophilos was particularly interested in the eye.
