Document Summary
Nervous tissue stimulates other cells (another neuron or muscle cell) by signaling using an impulse (electric current) [[table 4. 15]] Nuclei of glial (refers to family of cells) cells found in peripheral & central nervous system. There to nurture, nourish & support neurons. If you lose neuron that operates the muscle cell you might as well lose the muscle cell because they can"t operate anymore. Amylase is an enzyme found in saliva allows for the breakdown of large carbohydrates. Osteoclasts dissolve bone mobilizing calcium in spongy bone & compact bone. Orthodontics osteoclasts working to soften bone. Deposits additional fluid into those pleural/pericardial cavities cavities become real, before infection no cavity existed just serous fluid. 3 regions outer portion is called the epidermis (contains live & dead cells) Second layer dermis (larger of sections) Papillary layer & reticular layer different in tissue. Oil glands, hair follicles, muscle, blood vessel, sweat glands, nerve. Fig 5. 2 epidermis outer portion of skin receptors.
