digital veins – drain the digits and feed into your palmar arches on the hand and dorsal venous arch of the foot.
cuticle – in hair, the outermost layer of keratinocytes originating through the hair matrix, as seen in a very cross-part from the hair bulb.
basilic vein – superficial vein of the arm that occurs from the palmar venous arches, intersects Along with the median cubital vein, parallels the ulnar vein, and carries on into the higher arm; along with the brachial vein, it leads to the axillary vein.
cerebrum – location in the Grownup Mind that develops within the telencephalon and it is answerable for higher neurological features like memory, emotion, and consciousness.
Handle centre – compares values for their regular vary; deviations lead to the activation of the effector.
coronary sinus – huge, thin-walled vein about the posterior floor of your heart that lies inside the atrioventricular sulcus and drains the heart myocardium immediately into the proper atrium.
brain – the big organ in the central anxious process made up of white and gray make a difference, contained inside the cranium and constant With all the spinal twine.
basal nuclei – nuclei in the cerebrum (with a few parts inside the higher brain stem and diencephalon) that happen to be accountable for evaluating cortical motion commands and comparing them with the final point out of the individual through broad modulatory action of dopamine neurons; mostly related to motor features, as evidenced from the indicators of Parkinson’s and Huntington’s diseases.
atrioventricular bundle – (also, bundle of His) team of specialised myocardial conductile cells that transmit the impulse within the AV node throughout the interventricular septum; type the remaining and ideal atrioventricular bundle branches.
atrium – (plural = atria) upper or acquiring chamber from the heart that pumps blood into your decreased chambers just just before their contraction; the appropriate atrium gets blood from your systemic circuit that flows into the correct ventricle; the still left atrium receives blood in the pulmonary circuit that flows in to the still left here ventricle.

cytokines – class of proteins that act as autocrine or paracrine signalling molecules; from the cardiovascular system, they encourage the proliferation of progenitor cells and aid to promote the two nonspecific and precise resistance to condition.
Betz cells – output cells of the get more info first motor cortex that cause musculature to move by way of synapses on cranial and spinal motor neurons.
carbonic anhydrase (CA) – enzyme that catalyses the reaction that causes carbon dioxide and drinking water to kind carbonic acid.
