angiotensin II – protein made by the enzymatic motion of ACE on inactive angiotensin I; actively causes vasoconstriction and stimulates aldosterone release with the adrenal cortex.

basal lamina – skinny extracellular layer that lies beneath epithelial cells and separates them from other tissues.

cortical response – adhering to fertilisation, the release of cortical granules from your oocyte’s plasma membrane to the zona pellucida making a fertilisation membrane that forestalls any additional attachment or penetration of sperm; part of the sluggish block to polyspermy.

cleavage furrow – contractile ring that kinds close to a cell through cytokinesis that pinches the cell into two halves.

cervical vertebrae – 7 vertebrae numbered as C1–C7 that can be found during the neck region of the vertebral column.

central sulcus – floor landmark of your cerebral cortex that marks the boundary between the frontal and parietal click here lobes.

arrector pili – clean muscle that's activated in reaction to external stimuli that pull on hair follicles and make the hair “get up”.

cell cycle – daily life cycle of an individual mobile, from its start until its division into two new daughter cells.

amnion – transparent membranous sac that encloses the producing foetus and fills with amniotic fluid.

autorhythmicity – potential of cardiac muscle to initiate its individual electrical impulse that triggers the mechanical contraction that pumps blood at a fixed rate without having nervous or endocrine control.

immediate pathway – connections inside the basal nuclei with the striatum to the globus pallidus internal segment and substantia nigra pars reticulata that disinhibit the thalamus to enhance cortical control of movement.

cardiac reflexes – number of autonomic reflexes that enable the cardiovascular centres to regulate heart functionality centered on sensory info from a range of visceral sensors.

adductor tubercle – tiny, bony bump located around the superior aspect of the medial epicondyle with the femur.

allantois – finger-like outpocketing of yolk sac types the primitive excretory duct in read more the embryo; precursor on the urinary bladder.
