angiotensin II – protein made by the enzymatic action of ACE on inactive angiotensin I; actively will cause vasoconstriction and stimulates aldosterone release because of the adrenal cortex.
atlantoaxial joint – number of 3 articulations between the atlas (C1) vertebra and the axis (C2) vertebra, consisting of your joints in between the inferior articular processes of C1 and also the remarkable articular procedures of C2, and the articulation among the dens of C2 plus the anterior arch of C1.
atrioventricular bundle branches – (also, left or right bundle branches) specialised myocardial conductile cells that occur with the bifurcation from the atrioventricular bundle and go through the interventricular septum; result in the Purkinje fibres as well as to the best papillary muscle through the moderator band.
acrosome – cap-like vesicle located at the anterior-most region of a sperm that's loaded with lysosomal enzymes capable of digesting the protective layers surrounding the oocyte.
acromegaly – disorder in Grown ups triggered when abnormally high amounts of GH bring about progress of bones read more in the experience, palms, and toes.
blood–testis barrier – tight junctions between Sertoli cells that protect against bloodborne pathogens from getting entry to later stages of spermatogenesis and prevent the human anatomy and physiology definition likely for an autoimmune reaction to haploid sperm.
brain – the big organ of your central nervous technique composed of white and grey issue, contained within the cranium and continuous Using the spinal wire.
aponeurosis – broad, tendon-like sheet of connective tissue that attaches a skeletal muscle to a different skeletal muscle mass or to some bone.
angiotensin I – protein made by the enzymatic action of renin on angiotensinogen; inactive precursor of angiotensin II.
blood – liquid connective tissue made up of cellular elements—erythrocytes, leukocytes, and platelets—along with a fluid extracellular matrix known as plasma; component with the cardiovascular system.
apneustic centre – community of neurons inside the pons that stimulate the neurons during the dorsal respiratory group; controls the depth of inspiration.
dorsal arch – (also, arcuate arch) formed with the anastomosis with the dorsalis pedis artery and medial and plantar arteries; branches offer the distal parts with the foot and digits.
axon – one means of the neuron that carries an electrical signal (motion potential) clear of the mobile body towards a concentrate on mobile.
basal mobile – style of stem mobile located in the stratum basale and in the hair matrix that continually undergoes cell division, generating the keratinocytes in the epidermis.
