Ch.4: Tissues, Last part Flashcards
Highly cellular, well-vascularized tissues that are responsible for most types of body movements
Muscle tissues
Three kinds of muscle tissues are?
Skeletal muscles, Smooth Muscles, and Cardiac Muscle
Long, cylindrical multinucleate cells that contain striations. VOLUNTARY MOVEMENT
Skeletal muscle
Branching, Striated, generally uninucleate cells. Intercalated disc. found only in the walls of the heart
Cardiac muscle
Spindle-shaped cells with central nuclei, no striations INVOLUNTARY MOVEMENT
Smooth muscle
The main component of the nervous system, the brain , the spinal cord, and nerves. Regulate and control body functions
Nervous tissue
Highly specialized nerve cells that generate and conduct nerve impulses. CANNOT DIVIDE
neurons
Nourish,protect , and insulate the delicate neurons. Nonconducting. CAN DIVIDE
Neuroglial
The covering and lining membranes are of three types, they are ________
Serous, Cutaneous, and Mucous
Membrane that covers the body surface
Cutaneous membrane
Membrane that lines body cavities that are closed to the exterior
Serous membrane
Membranes that lines the body cavities that are open to the exterior
Mucous membranes
Repairs occurs in two major ways _______
Regeneration and fibrosis
List the 5 tissues that Regenerate extremely well
Epithelial tissue, bone, areolar connective tissue, dense irregular connective tissue, and blood-formin tissue
List the 2 tissues that have a moderate Regenerate capacity
Smooth tissue and dense regular connective tissue
List the 2 tissues that have a weak regenerative capacity
Skeltal muscles and cartilage
List the 2 tissues that have no functional regenerative capacity
Cardiac muscle, and nervous tissue
1st step to healing a wound
- inflammation
- blood vessels bleed
- blood vessels become more permeable to WBC
- clotting occurs, surface dries. Scab forms
2nd step to healing a wound
- Organization restores the blood supply
- clot replaced by granulation tissue
- collagen fibers bridge gap
- macrophages phagocytize debris
- epithelial cells multiply
final step to healing a wound
- Regeneration and Fibrosis
- scab detaches
- epithelium thickens
- fully regenerated epithelium with underlying scar tissue
Increase in size of existing cells in a tissue – Rigorous exercise or weight lifting
Hypertrophy
Increase in the number of cells – uterus during pregnancy,& callus
Hyperplasia
Shrinkage in size or number of cells of tissue
Atrophy
Abnormal tissue development can either revert to normal tissue or turn cancerous
Dysplasia
Abnormal tissue development – turns cancerous – benign or malignant
Neoplasia
Tissue death - Gangrene
Necrosis
4th Epithelial Membrane
Surround movable joint; produces synovial fluid
Arthritis: inflammation of _______ ________
Synovial Membrane
