Week 1 Tissues and Term

Four Types of Tissues

Epithelial tissue, Connective tissues, muscle tissue, nervous tissue

squamous

lattened and thin

cuboidal

boxy, as wide as it is tall

columnar

rectangular, taller than it is wide

Superior

towards the head

Inderior

away from the head; lower; below

Proximal

nearer trunk or point of origin

Distal

Away from trunk or point of origin

Medial

towards midline of the body

Lateral

away from midline of the body

Anterior / Ventral

Towards front of body

Posterior / Dorsal

towards back of body

Sagittal Cut (midsagittal / parasagittal)

sparating left and right

Transverse cut

separating superior and inferior

frontal cut

separating anterior and posterior

negative feedback

body reverse and negate a process

posirive feedback

amplifying cycle and lead to even greater changes in the same direction, child birth, blood clotting

Epithelium Tissue

sheet of cells, covers interior and exterior surfaces

Functions of Muscle

Locomotion / Stability / Communication / Control of body openings / Heat production / store glucose

Striated Muscle

Skeletal Muscle / Cardiac Muscle

Unstriated Muscle

Smooth muscle

Voluntary Muscle

Skeletal Muscle

Incoluntary Muscle

Cardiac Muscle / Smooth Muscle

Skeletal Muscle

Long, Cylindrical, Striated, Mulinucleated

Smooth Muscle

Short, spindle-shaped, nonstriated, one central nucleus

Cardiac Muscle

short, branched, striated, one nuclues

Three types of Connective Tissue

Connective Tissue Proper, Fluid Connective Tissue, Supporting Connective tissue
