The 2-Minute Rule for human anatomy and physiology

The adult human skeleton generally is made of 206 named bones. These bones might be grouped in two divisions: axial skeleton and appendicular skeleton.

cuticle – in hair, the outermost layer of keratinocytes originating within the hair matrix, as observed in a very cross-segment in the hair bulb.

coronary arteries – branches from the ascending aorta that supply blood on the heart; the still left coronary artery feeds the left facet of your heart, the still left atrium and ventricle, as well as interventricular septum; the ideal coronary artery feeds the best atrium, parts of both equally ventricles, as well as the heart conduction procedure.

central canal – longitudinal channel in the centre of each and every osteon; contains blood vessels, nerves, and lymphatic vessels; also called the Haversian canal.

cupula – specialised composition in the base of a semicircular canal that bends the stereocilia of hair cells when The top rotates Through the relative motion of the enclosed fluid.

blood hydrostatic pressure – power blood exerts versus the partitions of the blood vessel or read more heart chamber.

anterior tibial artery – branches from the popliteal artery; provides blood to the anterior tibial area; gets to be the dorsalis pedis artery.

counter present-day multiplier program – consists of the descending and ascending loops of Henle directing forming urine in opposing Instructions to create a concentration gradient when combined with variable permeability and sodium pumping.

Then the ATP is damaged down (catabolism) and also a managed level of Strength is unveiled, that's employed by the cell to accomplish a certain career.

autorhythmicity – capability of cardiac muscle to initiate its possess electrical impulse that triggers the mechanical contraction that pumps blood at a hard and fast tempo devoid of nervous or endocrine Handle.

blood colloidal osmotic tension (BCOP) – strain exerted by colloids suspended in blood in a vessel; a Major determinant is definitely the existence of plasma proteins.

dorsal arch – (also, arcuate arch) shaped from your anastomosis on the dorsalis pedis artery and medial and plantar arteries; branches source the distal portions of the foot and digits.

alkaloid – material, commonly from the plant source, that's chemically standard with regard to pH and will stimulate human anatomy organs bitter receptors.

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