Large, long, cylindrical cells; Multi-nucleated ; Attached to bones; Responsible for body movement
56
New cards
Cardiac Muscular Tissue
Cylindrical cells; Branched and connected to one another by intercalated disks; Single nucleated; Found in the heart; Pumps the blood
57
New cards
Smooth Muscular Tissue
End tapered cells; Single nucleated; Found in hollow organs: stomach, intestine; skin, eyes. Regulates size of organs, forces fluid through tubes, controls the amount of light entering the eye, produces ‘goose bumps’
58
New cards
Nervous Tissue
Found in the brain, spinal cord, and nerves; Responsible for coordinating and controlling
59
New cards
Action potentials
ability of nervous tissue cells to communicate with one another by means of electric signals
60
New cards
Neurons
responsible for conducting action potentials
61
New cards
Mucous Membrane
Consists of epithelium and loose connective tissues; Line the digestive, respiratory, reproductive tracts; Protection, absorption, secretion
62
New cards
Serous Membrane
\ Simple squamous epithelium and loose connective tissue; Line the trunk cavities and cover the organs within it; Serous fluid prevents damage from abrasion
63
New cards
Synovial Membrane
Formed by connective tissue; Line the inside of joint cavities
64
New cards
Inflammation
occurs when tissues are damaged
65
New cards
Histamine & Prostaglandins
chemical mediators of inflammation
66
New cards
Edema
swelling
67
New cards
Neutrophil
phagocytic WBC that fights infection
68
New cards
Pus
mixture of dead neutrophils, other cells, fluid
69
New cards
Chronic Inflammation
Results when the agent causing injury is not removed or something else interferes with the healing process
70
New cards
Regeneration
new cells are the same type as those that were destroyed
71
New cards
Fibrosis/Replacement
a new type of tissue develops that eventually causes scar production
72
New cards
Stem Cells
self‑renewing, undifferentiated cells that continue to divide throughout life
73
New cards
Clot
contains protein fibrin (binds the edges of a wound together and stops the bleeding)
74
New cards
Scab
dried surface of a clot; seals the wound and helps prevent infection
75
New cards
Granulation Tissue
delicate, granular appearing connective tissue that consists of fibroblasts, collagen, capillaries
