cartilage – semi-rigid connective tissue uncovered around the skeleton in locations wherever flexibility and clean surfaces support motion.
adrenaline – Major and many strong catecholamine hormone secreted via the adrenal medulla in reaction to brief-phrase strain.

atrioventricular (AV) node – clump of myocardial cells situated in the inferior portion of the best atrium inside the atrioventricular septum; gets the impulse with the SA node, pauses, and after that transmits it into specialised conducting cells in the read more interventricular septum.
Bachmann’s bundle – (also, interatrial band) team of specialised conducting cells that transmit the impulse straight from the SA node in the correct atrium towards the still left atrium.
atrioventricular bundle – (also, bundle of His) more info team of specialised myocardial conductile cells that transmit the impulse through the AV node with the interventricular septum; sort the remaining and ideal atrioventricular bundle branches.
dihydroxyvitamin D – Energetic method of vitamin D required with the intestinal epithelial cells for your absorption of calcium.
carpometacarpal joint – articulation in between among the carpal bones from the distal row and also a metacarpal bone with the hand.
bundle of His – (also, atrioventricular bundle) group of specialised myocardial conductile cells that transmit the impulse in the AV node in the interventricular septum; variety the still left and right atrioventricular bundle branches.
Of such capabilities, assist is among the most primitive and also the oldest; Also, the axial Portion of the skeleton was the primary to evolve. The vertebral column, similar to the notochord in lower organisms, is the principle assist of your trunk.
