cardiac skeleton – (also, skeleton of the heart) bolstered connective tissue Positioned inside the atrioventricular septum; incorporates four rings that encompass the openings amongst the atria and ventricles, and the openings for the pulmonary trunk and aorta; the point of attachment to the heart valves.
atlantoaxial joint – series of 3 articulations among the atlas (C1) vertebra and the axis (C2) vertebra, consisting from the joints involving the inferior articular processes of C1 as well as the exceptional articular procedures of C2, as well as the articulation concerning the dens of C2 plus the anterior arch of C1.
coronary arteries – branches on the ascending aorta that provide blood towards the heart; the still left coronary artery feeds the left side on the heart, the remaining atrium and ventricle, plus the interventricular septum; the proper coronary artery feeds the proper atrium, parts of both of those ventricles, as well as heart conduction procedure.
anticodon – consecutive sequence of a few nucleotides with a tRNA molecule that is definitely complementary to a particular codon on an mRNA molecule.

crista galli – little upward projection Found with the midline in the floor of the anterior cranial fossa; formed via the ethmoid bone.
anterior horn – gray matter from the spinal wire that contains multipolar motor neurons, often known as the ventral horn.
counter present-day multiplier procedure – consists of the descending and ascending loops of Henle directing forming urine in opposing Instructions to produce a concentration gradient when combined with variable permeability and sodium pumping.
atrial natriuretic peptide (ANP) – peptide hormone read more made by the walls of the atria in reaction to superior blood pressure level, blood quantity, or blood sodium that reduces the reabsorption of sodium and h2o while in the kidneys and encourages vasodilation.
acrosomal reaction – release of digestive enzymes by sperm that allows them to burrow through the corona radiata and penetrate the zona pellucida of an oocyte before fertilisation.
activation gate – click here A part of the voltage-gated Na+ channel that opens when the membrane voltage reaches threshold.
cardiac reflexes – number of autonomic reflexes that empower the cardiovascular centres to manage heart function based on sensory data from several different visceral sensors.
coronal suture – joint that unites the frontal bone to the proper and still left parietal bones through the prime in the skull.
alar plate – developmental area from the spinal wire that provides increase for the posterior horn with the gray matter.
