A Simple Key For human anatomy & physiology Unveiled

The Grownup human skeleton usually contains 206 named bones. These bones is usually grouped in two divisions: axial skeleton and appendicular skeleton.

cuticle – in hair, the outermost layer of keratinocytes originating in the hair matrix, as viewed in a very cross-section with the hair bulb.

bronchoconstriction – lower in the scale in the bronchiole because of contraction in the muscular wall.

costal cartilage – hyaline cartilage framework hooked up to the anterior end of each rib that provides for possibly direct or oblique attachment of most ribs to your sternum.

Reproduction is definitely the development of a new organism from parent organisms. In humans, reproduction is completed from the male and woman reproductive units. Because Demise will come to all elaborate organisms, devoid of reproduction, the road of organisms would conclusion.

enhance – enzymatic cascade of constitutive blood proteins which have antipathogen effects, including the immediate killing of bacteria.

anatomical posture – normal reference position used for describing spots and Instructions on the human body.

anterior median fissure – deep midline aspect in the anterior spinal twine, marking the separation in between the correct and still left sides of the wire.

The central nervous process lies largely within the axial skeleton, the Mind being properly protected with the cranium and the spinal wire from the vertebral column, by the use of the bony neural arches (the arches of bone that encircle the spinal twine) plus the intervening ligaments.

atrium – (plural = atria) higher or receiving chamber from the heart that pumps blood to the lessen chambers just just before their contraction; the correct atrium gets anatomy human body blood within the systemic circuit that flows into the proper ventricle; the still left atrium gets blood from your pulmonary circuit that flows into your still left ventricle.

anterior cardiac veins – vessels that parallel the smaller cardiac arteries and drain the anterior floor of the appropriate ventricle; bypass the coronary check here sinus and drain right into the ideal atrium.

artery – blood vessel that conducts blood from the heart; may be a conducting or distributing vessel.

deep femoral vein – drains blood through the further parts of the thigh and results in the femoral vein.

cerebral aqueduct – connection of your ventricular technique between the third and fourth ventricles situated in the midbrain.
