RAPID-adapting mechanoreceptors - ️️Meissner and Pacinian (dynamic phase QUICKLY becomes static phase) dorsal root ganglion (DRG) - ️️(part of the PNS) cluster of cell bodies in the dorsal root of a spinal nerve (when the action potential reaches the DRG, it splits into 2 - one travels toward the cell body and the other continues down the axon) dorsal horn - ️️the POSTERIOR column of grey matter in the spinal cord (shape differs depending on spinal segment) - contains SENSORY n...

actin - a protein that forms (together with myosin) the contractile filaments of muscle cells, and is also involved in motion in other types of cells-- THIN adduction - Adipose Tissue - cushion, insulate, store fat adipocytes anabolism - anabolism- provides the materials needed for cellular growth and repair dehydration synthesis anaphase - chromosomes separate and move to centrioles (opposite ends0 antagonists - resist prime movers action and cause movement in the opposite direction of ...
