cardiac skeleton – (also, skeleton on the heart) strengthened connective tissue located within the atrioventricular septum; consists of four rings that surround the openings among the atria and ventricles, and also the openings for the pulmonary trunk and aorta; The purpose of attachment for the heart valves.

diffusion – movement of a material from a region of better concentration to at least one of reduced concentration.

codon – consecutive sequence of a few nucleotides on an mRNA molecule that corresponds to a specific amino acid.

anticodon – consecutive sequence of a few nucleotides with a tRNA molecule that may be complementary to a selected codon on an mRNA molecule.

abdominal aorta – portion of the aorta inferior for the aortic hiatus and outstanding for the prevalent iliac arteries.

adrenal vein – drains the adrenal or suprarenal glands which might be quickly top-quality to the kidneys; the appropriate adrenal vein enters the inferior vena cava specifically plus the still left adrenal vein enters the still left renal vein.

Bainbridge reflex – (also, named atrial reflex) autonomic reflex that responds to stretch receptors during the atria that mail impulses into the cardioaccelerator space to enhance HR when venous stream to the atria raises.

Bachmann’s bundle – (also, interatrial band) group of specialised conducting cells that transmit the impulse directly from the SA node in the ideal atrium to the remaining atrium.

The central nervous technique lies mainly throughout the axial skeleton, the brain becoming very well protected with the cranium read more as well as spinal wire from the vertebral column, by way of the bony neural arches (the arches of bone that encircle the spinal twine) and also the intervening ligaments.

autorhythmicity – potential of cardiac muscle to initiate its possess electrical impulse that triggers the mechanical contraction that pumps blood at a hard and fast pace without having anxious or endocrine Handle.

adrenal cortex – outer area with the adrenal glands consisting of a number of levels of epithelial cells and capillary networks that generates mineralocorticoids and glucocorticoids.

When a single here considers the relation of these subdivisions in the skeleton towards the gentle areas of the human body—like the anxious system, the digestive method, the respiratory program, the cardiovascular method, and the voluntary muscles in the muscle mass program—it is clear that the capabilities with the skeleton are of 3 differing types: assistance, protection, and motion.

electronic arteries – formed with the superficial and deep palmar arches; supply blood on the digits.

basal cell – style of stem mobile found in the stratum basale and inside the hair matrix that frequently undergoes mobile division, creating the keratinocytes on the epidermis.
