Histology
the study of tissues
Mitosis and Meiosis
Mitosis and meiosis are the ways that cells reproduce. During mitosis, a cell duplicates
its DNA and divides into two identical cells called daughter cells. Meiosis, on the other
hand, produces four daughter cells that have only half of the chromosomes that the
parent cell has. Meiosis is the form of cell duplication that produces eggs and sperm.

membrane because it covers the body ; organ because it contains several kinds of

which attach bones to each other to form joints. Cardiac and smooth muscles are not
included in this organ system.

anatomic position
The position with the body erect with the arms at the sides and the palms forward. The

BALANCE, physical, emotional, cognitive, social;the "little brain" attached to the rear of
the brainstem; its functions include processing sensory input and coordinating
movement output and balance
Chyme
A pulpy mixture of food and gastric juices. Produced in the stomach, from which it
passes to the small intestine
Dermis
- the layer of the skin just below the epidermis, contains bundles of collogen, nerve
fibres, blood vessels, sweat glands, sebaceous glands & hair follicles
Distal
opposite of proximal; a particular body part is farther from the trunk or farther from
another specified point of reference than another part
Epidermis
Keratinized stratified squamous epithelium containing 4 distinct types of cells,
melanocytes(pigment)merkel cells(touch receptors)ketatinocytes(produce keratin) and
