Prorubricyte
24
are consistently the largest of the blood vascular elements often confused with large lymphocytes. They have a diameter of 12 to 15 um, ovoid nuclei, but are usually kidney or horseshoe shape and eccentrically placed and stained reddish purple. The cytoplasm is faint blue-gray with many small azurophilic granules and no specific granules.
Monocyte
25

Smooth muscles
27
are elongated, unbranched, cylindrical, multinucleated cells. The flattened peripheral nuclei lie just under the sarcolemma (muscle cell plasma membrane); most of the organelles and sarcoplasm (muscle cytoplasm) are near the poles of the nuclei. The sarcoplasm contains many mitochondria, glycogen granules, and an oxygen-binding protein called myoglobin, that accumulates lipofuscin pigments with age.
Skeletal muscle
27
A superfamily of motor proteins that are atp-dependent and responsible for actin-based motility. They are the thick filaments in the muscle fibrils
Myosin
28
Derived from the German term “Helles” which means clear. It is a lighter staining central region of the A band that contains the M line and only the thick filaments. It lies between the free ends of the thin filaments and contains only the shaft of myosin molecules
H-band
29
Linearly arranged functional subunits of muscles
Sarcomere
30
A collection of specialized synapse that transmits nerve impulses to muscle cells initiating muscle contraction
Neuromuscular junction / Motor end plate
31
Marks the center of each sarcomere and holds the thick filaments in place
M-line
31
Acts like insulation on a wire and greatly promotes speed and reliability of nerve impulse transmission
Myelin Sheath
32
Neuroglial cells that possess nuclei described as "string of pearls"
Satellite cells
33
It is the connective and supportive tissue of the cns located between the neurons
Supporting cells

37
They are layers of cells which cover the myelin sheath segments of some nerve cells and constrict at the node of ranvier
Schwann cells
38
Line the ventricular cavities of the brain and central canal of the spinal cord
Ependymal
39
They function by forming myelin sheaths around the axons in the white matter
Oligodendrocytes
40
Small constricted portion of neuron's myelin sheath which appear as gaps of narrowing along the axon
Node of Ranvier
41
It is composed of blocks of stacked rough endoplasmic reticulum
