The cells that are working together are called as
Tissues
What are the types of tissues
Epithelial
Connective
Muscle
Nervous
A type of tissue that primarily lines the body surfaces and body cavity
Epithelial tissue
A type of tissue that forms most of the gland
Epithelial tissue
Give some functions of epithelial tissue
Protection
Absorption, secretion, ion filtration
Forms slippery surfaces - inner part of the body
A type of tissue that is for lining and covering of organs and body surfaces
Epithelial tissue
A type of tissue that is for lining and covering of organs and body surfaces
Epithelial tissue
A type of tissue that is for supporting organs and body parts
Connective tisue
A type of tissue that is for supporting organs and body parts
Connective tisue
Most diverse and ABUNDANT type of tissue
Connective tissue
Most diverse and abundant type of tissue
Connective tissue
types or classes of connective tissue
connective tissue proper
blood (WBC types)
bone
cartilage
pathology means the study of ___
study of diseases
what are the Supporting connective tissues
cartilage and bone tissue
the supporting connective tissue that is subject for decalcification
Bone specimen
Components of connective tissue
cells and matrix
matrix is composed of
protein fibers and ground substances
Common embryonic origin
mesenchyme
Cells found in connective tissue proper
–Fibroblasts
–Macrophages, lymphocytes (antibody-producing cells)
–Adipocytes (fat cells)
–Mast cells
–Stem cells
youngest cell in the connective tissue proper
fibroblast
cells found in connective tissue proper that is primarily known as a scavenger of the cells through phagocytosis
Macrophages, lymphocytes
cells found in connective tissue proper that is also known as an antibody-producing cells
Macrophages, lymphocytes
we determine the adipocytes through _____ if its unilobular or multilobular
microscopic examination
Cells found in connective tissue proper that is particularly associated in the inflammation, healing, and repair
mast and stem cells
Types of Fibers in connective tissue
collagen
elastic
reticular
It’s along with fibers, and fills the extracellular space
ground substance
___ helps determine functionality of tissue
Ground substance
to summarize, what are the components of connective tisse
cells, ground substance and protein fibers
a type of protein fiber of connective tissue proper that is very strong & abundant, long & straight
collagen
a type of protein fiber of connective tissue proper that is a branching fibers with a wavy appearance (when relaxed )
elastic fibers
a type of protein fiber of connective tissue proper that form a network of fibers serving as a supportive framework in soft organs such as spleen and liver
reticular fibers
types of adipose tissue
White adipose tissue (WAT)
Brown adipose tissue (BAT )
is largely composed of
unilocular lipid-filled
adipocytes that specialize in
lipid storage
White adipose tissue (WAT)
is largely composed of
multilocular adipocytes that
specialize in lipid burning.
Brown adipose tissue (BAT)
muscle cells that are not regenerating
cardiac muscle
Characteristics of skeletal muscle tissue
– Long, cylindrical cells
–Multinucleate
–Obvious striation
do skeletal muscle cells have many nucleus
yes
function of skeletal muscle tissue
–Voluntary movement
–Facial expression
Location of skeletal muscle tissue
attached to bones (occasionally to skin)
can myocytes regenerate?
nope, permanent damage
characteristics of cardiac muscle
–Branching cells
–Uni-nucleate
–Intercalated discs
a muscle tissue that is for contraction to propel blood into circulatory system
cardiac muscle tissue
Location of cardiac muscle
walls of the heart
specialized structure in cardiac muscle, responding to myocardial infarction
intercalated disk
a cardiac marker for myocardial infarction (TROPONIN) which one is the specific for MI
troponin I
Characteristics of smooth muscle
–Spindle-shaped cells with
central nuclei
–Arranged closely to form
sheets
–No striations
Location of smooth muscle
walls of hollow organs
a muscle tissue that Propels substances along
internal passageways
Smooth Muscle Tissue
muscle tissue that are involuntarily controlling muscles
smooth and cardiac
