Cell Types Flashcards
form the covering of surfaces of the body located both in internal and external parts
epithelial tissue
1) protection of the underlying tissues,
(2) absorption,
(3) secretion, and
(4) reception of sensory stimuli.
epithelial tissue
Based on number of cell layers
Simple
Stratified
Pseudostratified
epithelial tissue
Based on shape of cells
Squamous
Cuboidal
Columnar
epithelial tissue
thin, scaly-look like, flattened on the surface, fried-egg appearance with rounded nucleus function: diffusion
filtration
secretion
protection
location: kidney
air sacs
lining of heart
squamous cell
dice shape, square-like shape with large and spherical nuclei
function: secretion
absorption
location: kidney tubules
egg cells
ducts and secretory position of small glands.
cuboidal cell
taller rather than wide, column in shape, long and rectangular shape with oblong nuclei or elongated nucleus
function: absorption
secretion
reception
sensory
location: digestive tubes
gallbladder
uterine tubes
uterus
nose, ears, tongue
columnar cell
move mucus and other substance across the cell, ciliary action
function: fine hair-like projection location: nose
uterus, fallopian tube,s, egg cells
ciliated columnar cell
false stratification or appearance, free surfaces with hair-like projection, nuclei seen at different level
function: filtration
absorption
secretion
ciliary action
location: ducts of large glands
ductus difference
trachea, throat, mouth
pseudostratified columnar cell
use to connect, bind, hold, and support one part to another part of the body.
most vascularized and widely distributed inside the body
characterized by a large percentage of living cells and non-living material known as matrix which is made of ground substance and fibrous structures
connective tissue
hard or calcified
support, protects, provides lever, storage, hematopoiesis
Bone cell (osteocytes)
bone tissue
support, cushion properties
firm, collagenous fibers
chondrocytes
hylaine cartilage
absorb compressive shock
chondrocytes
collagenous fibers
fibro cartilage
support the external
elastic fibers
chondrocytes
elastic cartilage
gel-like matrix, collagen fibers, elastic fibers
holds and conveys tissue fluid, inflammation
mast cells, white blood cells, fibroblasts, macrophages
areolar cartilage
fat cells, adipocytes
reticular, collagen
adipose tissue
rubbery, collagen, elastic fibrous secretion of chondroitin substance
support, helps to provide structures
chondrocytes
cartilage tissue
collagen structure, elastic
holding the organs in a particular area
fibroblasts
areolar tissue
storage of lipids for energy building
fat cell (adiposytes)
reticular structure with collagenous fibers
adipose tissue
composed of muscle cells that are designed for contraction and movement
inside the muscle fiber or a muscle cell is consists of sarcoplasm known as the cell membrane, sarcolemma as the cytoplasm of the muscle cell and the cell body that containing nucleus located at the center
muscle tissue
Long cylindrical shape, bundle forms, many nucleus, many striations
Skeletal muscles
STRIATED/ VOLUNTARY/ SKELETAL MUSCLE CELLS
short branching shape
have few striations
single nucleus/two nucleus
Heart/ cardiac muscle
STRIATED/ INVOLUNTARY/ CARDIAC MUSCLE CELLS
spindle in shape of cells
one nucleus located at the center
no striations
visceral/ smooth muscle tissue
NON-STRIATED/ INVOLUNTARY/ SMOOTH MUSCLE CELLS
Consists of two types of cells:
Conducting cells - aka neurons are modified to respond to specific stimuli.
Supportive cells – aka neuroglia; It transports nutrients from the blood vessels to neurons and guard against toxin by creating barrier to many harmful substances.
nervous tissue
The ability to respond to stimuli is one of the characteristic of living things.
irritability
which contains nucleus that is located at the center and its function is to control the entire activities of the neuron.
cell body or soma
The ability to transmit an impulse
conductivity
that composed of collectively nerve fibers that also made up of the dendrites and axon.
processes
these are the short branch located around the nucleus and conducts electrical impulses toward the cell body.
dendrites
contains a single long branch that is responsible of conducting impulses away from the cell body.
axon
is known as the cell membrane
axolemma
is the cytoplasm of the neuron
axoplasm
he plasma membrane of the Schwann cell
neurilemma
