The adult human skeleton usually includes 206 named bones. These bones is often grouped in two divisions: axial skeleton and appendicular skeleton.
capsaicin – molecule that activates nociceptors by interacting by using a temperature-delicate ion channel and is the basis for “very hot” sensations in spicy food stuff.
coronary arteries – branches of the ascending aorta that supply blood towards the heart; the left coronary artery feeds the remaining aspect on the heart, the remaining atrium and ventricle, along with the interventricular septum; the correct coronary artery feeds the right atrium, parts of both ventricles, plus the heart conduction method.
anticodon – consecutive sequence of 3 nucleotides over a tRNA molecule that is certainly complementary to a selected codon on an mRNA molecule.
cervical vertebrae – seven vertebrae numbered as C1–C7 that are located inside the neck area from the vertebral column.
adrenal medulla – inner layer of your adrenal glands that plays an important position inside the strain response by making adrenaline and noradrenaline.
calyces – cup-like constructions acquiring urine in the accumulating ducts where by it passes on to your renal pelvis and ureter.
anterior interventricular sulcus – sulcus Found amongst the left and appropriate ventricles on the anterior area with here the heart.
Cells, such as, Use a cell membrane (also known as the plasma membrane) that keeps the intracellular atmosphere—the fluids and organelles—individual from the extracellular setting. Blood vessels retain blood inside of a closed circulatory procedure, and nerves and muscles are wrapped in connective tissue sheaths that individual them from surrounding structures.
cervical curve – posteriorly concave curvature in the cervical vertebral column location; a secondary curve of the vertebral column.
ABO blood team – blood-kind classification depending on the presence or absence of A and B carbohydrates within the erythrocyte membrane area.
corneal reflex – protective response to stimulation with the cornea triggering contraction of your orbicularis oculi muscle mass resulting check here in blinking of the attention.
abducens nerve – sixth cranial nerve; answerable for contraction of one of many extraocular muscles.
complete refractory period of time – time throughout an motion interval when An additional motion potential can not be generated because the voltage-gated Na+ channel is inactivated.
