cardiac skeleton – (also, skeleton on the heart) strengthened connective tissue located inside the atrioventricular septum; contains 4 rings that surround the openings in between the atria and ventricles, along with the openings on the pulmonary trunk and aorta; the point of attachment for the heart valves.

annular ligament – intrinsic ligament on the elbow articular capsule that surrounds and supports The top from the radius within the proximal radioulnar joint.

basilic vein – superficial vein of your arm that arises with the palmar venous arches, intersects Along with the median cubital vein, parallels the ulnar vein, and continues in the upper arm; combined with the brachial vein, it causes the axillary vein.

biogenic amine – class of neurotransmitters which are enzymatically derived from amino acids but no more comprise a carboxyl group.

control centre – compares values for their regular array; deviations result in the activation of the effector.

Brodmann’s spots – mapping of locations on the cerebral cortex determined by microscopic anatomy that relates precise locations to functional variations, as described by Brodmann inside the early 1900s.

Bainbridge reflex – (also, referred to as atrial reflex) autonomic reflex that responds to stretch receptors in the atria that mail impulses into the cardioaccelerator spot to boost HR when venous flow into your atria improves.

chemical synapse – connection involving two neurons, or in between a neuron and its target, the place a neurotransmitter diffuses throughout an extremely limited length.

aortic arch – arc that connects the ascending aorta to your descending aorta; finishes with the intervertebral disk between the fourth and fifth thoracic vertebrae.

cranial nerve – certainly one of twelve nerves linked to read more the brain which might be liable for sensory or motor features of The pinnacle and neck.

bundle of His – (also, atrioventricular bundle) team of specialised myocardial conductile cells that transmit the impulse from your AV node through the interventricular septum; variety the still left and correct atrioventricular bundle branches.

A particular attribute of humans as in contrast with other website mammals is erect posture. The human body is usually to some extent like a strolling tower that moves on pillars, represented because of the legs. Great pros happen to be received from this erect posture, the chief amongst which has been the releasing with the arms for a great variety of takes advantage of.

anterior corticospinal tract – division with the corticospinal pathway that travels from the ventral (anterior) column with the spinal cord and controls axial musculature in the medial motor neurons in the ventral (anterior) horn.
