cardiac skeleton – (also, skeleton with the heart) bolstered connective tissue Situated within the atrioventricular septum; contains four rings that surround the openings in between the atria and ventricles, plus the openings to your pulmonary trunk and aorta; the point of attachment to the heart valves.
diffusion – movement of a material from a place of better concentration to one of decreased focus.
coronary arteries – branches from the ascending aorta that supply blood towards the heart; the remaining coronary artery feeds the left aspect with the heart, the left atrium and ventricle, along with the interventricular septum; the best coronary artery feeds the appropriate atrium, portions of the two ventricles, and the heart conduction method.
biogenic amine – class of neurotransmitters which can be enzymatically derived from amino acids but no longer comprise a carboxyl team.

anterior column – white make any difference concerning the anterior horns with the spinal wire made up of many alternative groups of axons of each ascending and descending tracts.
choroid plexus – specialised structure made up of ependymal cells that line blood capillaries and filter blood to produce CSF inside the four ventricles of the Mind.
anterior interventricular sulcus – sulcus Positioned involving the remaining and right read more ventricles within the anterior surface area in the heart.
axoplasm – cytoplasm of the axon, which differs in composition compared to cytoplasm in the neuronal cell body.
blood – liquid connective tissue composed of cellular parts—erythrocytes, leukocytes, and platelets—along with a click here fluid extracellular matrix identified as plasma; component on the cardiovascular procedure.
activation gate – Component of the voltage-gated Na+ channel that opens once the membrane voltage reaches threshold.
arachnoid trabeculae – filaments involving the arachnoid and pia mater in the subarachnoid Place.
alkaloid – compound, typically from a plant resource, that is chemically fundamental with regard to pH and can promote bitter receptors.
basement membrane – in epithelial tissue, a skinny layer of fibrous materials that anchors the epithelial tissue to your underlying connective tissue; designed up in the basal lamina and reticular lamina.
