Cards

Term
epithelium tissue
Definition
lining and covering tissues
(line all hallow organs/structures, very little matrix)
Term
muscular tissue
Definition
produces force or movement
(movement of body parts or fluid)
Term
nervous tissue
Definition
sends signals
(impulses -electrical- or chemical, coordinates body activities)
Term
connective tissue
Definition
largest and most diverse category of tissue
(has lots of matrix)
Term
simple epithelium
Definition
one layer of epithelium
Term
stratified epithelium
Definition
several layers of epithelium
Term
simple squamous epithelium
Definition
single layer of flat cells
(found lining blood vessels and alveoli of lungs)
Term
stratified squamous epithelium
Definition
several cell layers - thick deeper cells are kind of blocky, and upper cell layers are flat
(found in places that are subject to abrasion -skin, oral cavity, rectum)
Term
simple cuboidal epithelium
Definition
one layer of blocky cells
(found forming ducts of many glands)
Term
simple columnar epithelium
Definition
single layer of tall and narrow cells - all nuclei are at same height
(found lining of stomach and intestines)
Term
pseudostratified columnar epithelium
Definition
one layer of tall cells that seem like several layers - nuclei at different heights
(found lining airways of respiratory system)
Term
loose (areolar) connective tissue
Definition
scattered arrangement of fibers,
weakest of all c.t.
(bodies packing material)
Term
connective tissue proper
Definition
connective tissue that connects structures and fills in spaces
(very flexible)
Term
dense irregular connective tissue
Definition
collagen fibers don't run parallel,
forms tough layer in many different directions
(dermis of skin)
Term
dense regular connective tissue
Definition
collagen fibers run parallel,
(found in tendons and ligaments)
Term
tendons
Definition
type of dense regular c.t.
connects muscle to bone
Term
ligaments
Definition
type of dense regular c.t.
connects bone to bone
Term
adipose tissue
Definition
fat tissue
(for storing energy and cushioning)
Term
supporting connective tissue
Definition
tissues that are stiff or rigid,
helps provide framework and shape for body
Term
cartilage
Definition
type of supporting c.t.
stiff but flexible,
normally has no blood vessels
Term
hyaline cartilage
Definition
type of cartilage (most common),
(protects at joints and supports air passages)
Term
elastic cartilage
Definition
type of cartilage (least common),
more flexible and resilient
(found in voice box and auricle of ear)
Term
fibrous cartilage
Definition
type of cartilage,
no blood vessels
(found in knee and between vertebrae)
Term
bone
Definition
type of supporting connective tissue
hardest tissue of body, matrix is full of calcium salt crystals, has right blood supply
Term
dense bone
Definition
type of bone,
all space filled with bone
Term
spongy bone
Definition
type of bone,
space has spongy area not filled with bone tissue
Term
blood
Definition
fluid connective tissue,
made of several types of cells and liquid matrix (plasma)
Term
muscular tissue
Definition
force and movement production tissue of body, works by pulling (can only produce motion or force in one direction)
Term
skeletal muscle tissue
Definition
most common type of tissue in body,
attached to bones (muscle that moves skeleton), can be moved voluntarily, cells are long and straited
Term
cardiac muscle tissue
Definition
straited and cells connected by intercalated discs, only found in heart, involuntary muscle
Term
smooth muscle tissue
Definition
cells are not straited and short/cylindrical, found surrounding many hallow organs, involuntary muscle,
(ex. wall of stomach and large intestines)
Term
nervous tissue
Definition
tissue that makes up nervous system
Term
neurons
Definition
main functional cells (signaling and coordinating cells)
Term
neuroglial cells
Definition
support cells of nervous system, physically anchor and support neurons, perform maintenance
