articular capsule – connective tissue structure that encloses the joint cavity of the synovial joint.

continual conduction – gradual propagation of the action potential along an unmyelinated axon owing to voltage-gated Na+ channels Positioned alongside all the size in the mobile membrane.

atrioventricular bundle branches – (also, still left or proper bundle branches) specialised myocardial conductile cells that crop up within the bifurcation on the atrioventricular bundle and go through the interventricular septum; lead to the Purkinje fibres and likewise to the best papillary muscle by way of the moderator band.

basal plate – developmental area from the spinal cord that offers rise on the lateral and anterior horns of gray matter.

afterload – force the ventricles need to produce to proficiently pump blood in opposition to the resistance while in the vessels.

atrial reflex – (also, termed Bainbridge reflex) autonomic reflex that responds to extend receptors within the atria that send out impulses on the cardioaccelerator location to enhance HR when venous circulation in the atria increases.

atrioventricular (AV) node – clump of myocardial cells situated in the inferior portion of the appropriate atrium inside the atrioventricular septum; receives the impulse through the SA node, pauses, after which you can transmits it into specialised conducting cells within the interventricular septum.
