5 Simple Techniques For human anatomy and physiology definition

decussate – to cross the midline, as in fibres that task from 1 side in the body to another.

steady conduction – sluggish propagation of an motion likely along an unmyelinated axon owing to voltage-gated Na+ channels located alongside the complete size with the mobile membrane.

denaturation – loss of form in a protein due to modifications in temperature, pH, or chemical publicity.

distal convoluted tubules – portions in the nephron distal on the loop of Henle that receive hyposmotic filtrate with the loop of Henle and empty into collecting ducts.
