A list of reflexes in humans. *Accommodation reflex — coordinated changes in the vergence, lens shape and pupil size when looking at a distant object after a near object. *Acoustic reflex or stapedius reflex or attenuation reflex — contraction of the stapedius and tensor tympani muscles in the middle ear in response to high sound intensities. *Ankle jerk reflex — jerking of the ankle when the Achilles tendon is hit with a tendon hammer while the foot is relaxed, stimulating the S1 reflex arc. *Arthrokinetic reflex — muscular activation or inhibition in response to joint mobilization *Asymmetric tonic neck reflex (ATNR) or tonic neck reflex — in infants up to four months of age, when the head is turned to the side, the arm on that side will straighten and the contralateral arm will bend. *Babinski reflex — in infants up to one year of age, and also in older individuals with neurological damage, a spreading of the toes and extension of the big toe in response to stroking the side of the foot. *Baroreflex or baroreceptor reflex — homeostatic countereffect to a sudden elevation or reduction in blood pressure detected by the baroreceptors in the aortic arch, carotid sinuses, etc. *Bezold-Jarisch reflex — involves a variety of cardiovascular and neurological processes which cause hypopnea and bradycardia. *Biceps reflex — a jerking of the forearm when the biceps brachii tendon is struck with a tendon hammer, stimulating the C5 and C6 reflex arcs. *Blushing — a reddening of the face caused by embarrassment, shame, or modesty. *Brachioradialis reflex — a jerking of the forearm when the brachioradialis tendon is hit with a tendon hammer while the arm is resting, stimulating the C5 and C6 reflex arcs. *Cervico-collic reflex *Cervico-Spinal reflex *Churchill cope reflex *Corneal reflex — blinking of both eyes when the cornea of either eye is touched. *Cough reflex — a rapid expulsion of air from the lungs after sudden opening of the glottis, and usually following irritation of the trachea. *Cremasteric reflex — elevation of the scrotum and testis elicited by stroking of the superior and medial part of the thigh. *Crossed extensor reflex — a contraction of a limb in response to ipsilateral pain, and extension of the contralateral limb. *Galant reflex — in infants up to four months of age, a rotation of the upper body towards one or other side of the back when that side is stroked. *Glabellar reflex *Golgi tendon reflex *Hering–Breuer_reflex — is a reflex triggered to prevent over-inflation of the lung *Jaw jerk reflex *Knee jerk or patellar reflex — a kick caused by striking the patellar tendon with a tendon hammer just below the patella, stimulating the L4 and L3 reflex arcs. *Mammalian diving reflex *Moro reflex — only in all infants/newborns up to 4 or 5 months of age: a sudden symmetric spreading of the arms, then unspreading and crying, caused by an unexpected loud noise or the sensation of being dropped. It is the only unlearned fear in humans. *Palmar grasp reflex — in infants up to six months of age, a closing of the hand in response to an object being placed in it. *Photic sneeze reflex — a sneeze caused by sudden exposure to bright light. *Plantar reflex — in infants up to 1 year of age, a curling of the toes when something rubs the ball of the foot. *Pupillary accommodation reflex — a reduction of pupil size in response to an object coming close to the eye. *Pupillary light reflex — a reduction of pupil size in response to light. *Rooting reflex — turning of an infant's head toward anything that strokes the cheek or mouth. *Shivering — shaking of the body in response to early hypothermia in warm-blooded animals. *Sneeze or sternutation — a convulsive expulsion of air from the lungs normally triggered by irritation of the nasal mucosa in the nose. *Startle reflex — see Moro reflex above. *Sternutation — see Sneeze above. *Suckling reflex — sucking at anything that touches the roof of an infant's mouth. *Stretch reflex *Triceps reflex — jerking of the forearm when the triceps tendon is hit with a tendon hammer, stimulating the C7 and C6 reflex arcs. *Vagovagal reflex — contraction of muscles in the gastrointestinal tract in response to distension of the tract following consumption of food and drink. *Vestibulocollic reflex *Vestibulo-spinal reflex *Vestibulo-ocular reflex — movement of the eyes to the right when the head is rotated to the left, and vice versa. *Yawn ==References== * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of reflexes」の詳細全文を読む スポンサード リンク
