Median plane (midsagittal)
splits the body into left and right
Frontal plane
divides the body into anterior and posterior parts
Transverse plane
splits the body into superior and inferior parts
Dorsal cavity
contains the brain and spinal cord
Thoracic Cavity
Heart and lungs
Abdominal Cavity
Digestive organs
Pelvic Cavity
Bladder, reproductive organs, and Rectum
The 4 Abdominal Cavity Quadrants
Right upper, Right lower, left upper, left lower
Squamous Cell
flat with a nucleus in the center
Cuboidal
Cube like shape with a spherical nucleus
Columnar
Column like, with oval nucleus
Where is Squamous found?
Main Function: filtration
kidneys, air sacs in the lungs, blood vessels
Where is cuboidal found?
Main function: Absorption
Ducts of secretory glands, ovary surfaces
Where is columnar found?
Main function: Absorption, secretion of mucus
Digestive tract, gallbladder
Characteristics of connective tissue
Function: protect, insulate, support and bind tissues to the body (epithelial tissue)
What are the four main types of Connective Tissue
loose/dense connective tissue
cartilage
bone
blood
Vascularity
rich blood supply
Extracellular matrix
a non-living material, which lies between connective tissue cells.
Ground substance
composed of fluid like substance, as well as proteins
Fibers
provide support to the connective tissue
collagen, elastic, and reticular fibers
Areolar
Loose connective, cushions organs, under epithelia
Adipose
Loose connective, insulates, support and protect organs, energy for fuel, underneath the skin
Regular
Dense, Attaches muscle to bone or other muscle, in tendons and ligaments
Irregular
Dense, withstand tension, provides strength
Osseous (Bone)
Support, stores calcium, minerals, and fat
Layers of the Skin
Epidermis, Dermis, Hypodermis
Epidermal layers (outer to inner)
Stratum corneum, stratum lucid (only in thick skin) stratum graunlosum, stratum spinosum, stratum basale
