angiotensin II – protein produced by the enzymatic motion of ACE on inactive angiotensin I; actively brings about vasoconstriction and stimulates aldosterone launch via the adrenal cortex.
atlantoaxial joint – number of a few articulations involving the atlas (C1) vertebra along with the axis (C2) vertebra, consisting with the joints amongst the inferior articular procedures of C1 and the remarkable articular processes of C2, as well as the articulation involving the dens of C2 as well as anterior arch of C1.
cartilage – semi-rigid connective tissue uncovered around the skeleton in parts the place versatility and sleek surfaces assist motion.
motion opportunity – transform in voltage of a mobile membrane in response into a stimulus that ends in transmission of the electrical sign; exceptional to neurons and muscle mass fibres.
anterior cranial fossa – shallowest and many anterior cranial fossa in the cranial base that extends from your frontal bone on the lesser wing on the sphenoid bone.
adrenal medulla – inner layer on the adrenal glands that performs an essential purpose during the worry reaction by producing adrenaline and noradrenaline.
The first law of thermodynamics retains that Electrical power can neither be made nor wrecked—it could only change sort. Your primary operate as an organism should be to eat (ingest) Power and molecules in the foods you try to eat, convert many of it into fuel for motion, sustain your human anatomy diagram body capabilities, and Construct and maintain your body constructions. There are 2 forms of reactions that execute this: anabolism and catabolism.
cornea – fibrous covering from the anterior region of the attention that may be transparent so that light can pass through it.
aortic arch – arc that connects the ascending aorta to the descending aorta; finishes on the intervertebral disk in between the fourth and fifth thoracic vertebrae.
Marathon Runners Runners show two properties of residing humans—responsiveness and movement. Anatomic structures and physiological procedures let runners to coordinate the motion of muscle mass groups and sweat in response to increasing inside body temperature. (credit: Phil Roeder/flickr)
acromion – flattened bony approach that extends laterally within the scapular backbone to type the bony idea of your shoulder.
cytokines – class of proteins that act as autocrine or paracrine signalling molecules; within the cardiovascular program, they stimulate the proliferation of progenitor cells click here and aid to encourage both equally nonspecific and certain resistance to illness.
Broca’s location – region on the frontal lobe connected to the motor instructions essential for speech creation and located only in the cerebral hemisphere responsible for language output, and that is the remaining side in close to 95 per cent of the populace.
anterior corticospinal tract – division with the corticospinal pathway that travels through the ventral (anterior) column on the spinal wire and controls axial musculature with the medial motor neurons while in the ventral (anterior) horn.
