anterior cerebral artery – occurs from the internal carotid artery; provides the frontal lobe with the cerebrum.
appendicular skeleton – all bones of the higher and decreased limbs, as well as the girdle bones that attach Each individual limb for the axial skeleton.
atrioventricular bundle branches – (also, remaining or ideal bundle branches) specialised myocardial conductile cells that occur in the bifurcation on the atrioventricular bundle and pass through the interventricular septum; lead to the Purkinje fibres as well as to the ideal papillary muscle mass via the moderator band.
dentin – bone-like tissue promptly deep to your enamel of the crown or cementum of the root of the tooth.
Safety in the heart, lungs, and various organs and buildings within the upper body creates a challenge considerably unique from that from the central nervous method. These organs, the function of which consists of motion, growth, and contraction, must have a flexible and elastic protecting covering. This type of covering is furnished by the bony thoracic basket, or rib cage, which sorts the skeleton on the wall from the more info chest, or thorax.
blood hydrostatic stress – pressure blood exerts towards the walls of a blood vessel or heart chamber.
atrioventricular (AV) node – clump of myocardial cells situated in the inferior percentage of the right atrium inside the atrioventricular septum; gets the impulse in the SA node, pauses, and then transmits it into specialised conducting cells throughout the interventricular septum.
coracoid method – small, hook-like procedure that initiatives anteriorly and laterally in the remarkable margin from the scapula.
Cells, for example, Have got a cell membrane (also referred to as the plasma membrane) that retains the intracellular natural environment—the fluids and organelles—different within the extracellular setting. Blood vessels keep blood inside of a shut circulatory process, and nerves and muscles are wrapped in connective tissue sheaths that individual them from encompassing structures.
artificial pacemaker – clinical device that transmits electrical indicators to the heart to make sure that it contracts and pumps blood for the body.
anterior cardiac veins – vessels that parallel the modest cardiac arteries and drain the anterior surface of the appropriate ventricle; bypass the coronary sinus and drain specifically into the appropriate atrium.
cerebral peduncles – segments on the descending motor pathway which make check here up the white matter in the ventral midbrain.
axon – solitary means of the neuron that carries an electrical signal (motion possible) far from the mobile body toward a goal cell.
coronoid fossa – despair within the anterior area of the humerus over the trochlea; this Room receives the coronoid strategy of the ulna when the elbow is maximally flexed.
