CHAPTER 5: Part 1 Flashcards
cells that have ability to divide without limit and give rise to specialized cells
stem cells
somato
body
forms the covering of both internal and external surfaces (skin and lining of cavities). cells are joined by small amounts of cementing substances.
epithelial tissue
supports and binds other body tissue and parts. (bone and fat cells, for example)
connective tissue
is composed of fibers that are able to contract, causing movement of body parts and organs.
muscular tissue
conducts impulses that connect the brain and spinal cord with other parts of the body.
nervous tissue
consists of several organs that work together to accomplish a set of functions
body system
refers to the constant internal environment that is naturally maintained by the body.
homeostasis
homeo
sameness
-stasis
controlling
a-
without
-plasia
formation
dys
bad
hypo
below nowmal
hyper
above normal
the lack of development of an organ or tissue
aplasia
any abnormal development of tissues, recognized by cells that differ in size, shape and appearance.
dysplacia
underdevelopment of an organ or a tissue, and is less severe than aplasia
hypoplasia
an increase in the size of an organ caused by an increase in the size of existing cells rather than the number of cells (as in hyperplasia)
hypertrophy
is characteristic of malignant tumors
anaplasia
hyper
more than normal
-trophy
nutrition
-plasia
formation
the position that a person is in while standing erect with the arms at the sides and the palms forward.
anatomic position
nearer to or toward the front; ventral
anterior
nearer to or toward the back; dorsal; situated behind
posterior
belly side; same as anterior surface in humans
ventral
directed toward or situated on the back side; same as posterior surface in humans
dorsal
middle or near the middle
medial, median
toward the side; denoting a position farther from the midline of the body or from a structure
lateral
uppermost or above
superior
lowermost or below
inferior
nearer the origin or point of attachment
proximal
far or distant from the origin or point of attachment
distal
toward the head
cephalad
toward the tail or an inferior direction in humans
caudad
inside, within
internal
outside
external
divides the body into front and back portion
frontal plane
divides the body into upper and lower portions
transverse plane
divides the body into right and left sides
sagittal plane
