#medblr notes

Number biceps = two triceps = three quadriceps = four

Shape delt- = triangular trapez- = trapezoid serra- = saw-toothed rhombo- = rhomboid

Direction of Muscle Fibers rectus = parallel transverse = perpendicular oblique = angled

Neutrophil -- lifespan of 7 hours -- immune defenses

Eosinophil -- lifespan of 8 to 12 days -- defense against parasites

Basophil -- lifespan of a few hours to a few days -- inflammatory response

Monocytes -- lifespan of 3 days -- immune surveillance

B-lymphocyte -- may live for many years -- antibody production

Hypotonic -- the cells inflate and eventually burst -- too much water is transported into the cell

Isotonic -- the amount of water transported into the cell is equal to the amount of water transported out from the cell -- the “normal” blood cell -- solute concentration inside the cell is equal to the solution outside the cell

-- there are three types of junctions:      -- tight      -- desmosome      -- gap

-- tight junctions seal epithelial cells to one another

-- desmosomes have “spotted” seals, where keratin filaments anchor the two cells

Hinge -- in one place about a single axis, like the movement of a hinged door

Pivot -- rotation

Ball and Socket -- widest range of all joints

Condyloid (Ellipsoidal) -- in two places at right angles to each other

Saddle -- same kinds of movement as condyloid joints, but freer; resembles rider in saddle

Flexion -- the decreasing angle between two bones

Abduction -- the movement of a body part away from a midline

Medial Rotation -- the turning of a bone on its own axis toward the midline of the body

Supination -- the placing of the palm of the hand in the anatomical position

Elevation -- the raising of a body part

Protraction -- the thrusting forward of a body part

Dorsiflexion -- the bending of the foot toward the shin
