ANAPHY PRELIM REVIEWER Flashcards
a group of cells that usually have a common
origin in an embryo and function together to carry
out specialized activities.
TISSUE
science that deals with the study
of tissues.
HISTOLOGY
a physician who specializes in
laboratory studies of cells and tissues to help other
physicians make accurate diagnoses.
PATHOLOGIST
Types Of Tissues (4) ECMN
epithelial, connective, muscular, nervous
contact points
between the plasma membranes
of tissue cells.
cell junctions
Also known as Occluding Junctions or
Zonula Occludens
Tight Junctions
consist of web-like strands of
transmembrane proteins that fuse together the
outer surfaces of adjacent plasma membranes to
seal off passageways between adjacent cells.
Tight Junctions
Adherens junctions contain plaque, a dense layer
of proteins on the inside of the plasma membrane
that attaches both to membrane proteins and to
microfilaments of the Cytoskeleton.
Adherens Junctions
transmembrane glycoproteins that
joins the cells.
Cadherins
responsible for its resilience; bone
collagenous fibers:
responsible for its
hardness; bone
calcified ground substance
calcified ground substance is mainly made up of
calcium phosphate
active in bone formation; immature
osteoblasts
principal cells of mature bone
osteocytes
active in bone resorption
osteoclasts
allow for growth of long bone
during childhood
epiphyseal plates
bone is a what type of connective tissue?
special connective tissue
Hormonal Regulation; Released when blood calcium level is low
*Increased: results to bone resorption
parathyroid hormone
Released when blood calcium level is high
Inhibits bone resoprtion
Calcitonin
2 types of bone tissue
compact, cancellous(spongy)
with many spaces, red
bone marrow where
hematopoiesis takes place
cancellous (spongy)
5 shape of bones
long, short, flat, irregular, sesamoid
enclosed in tendon and fascial
tissue and are found
adjacent to joints
sesamoid
consist of a shaft, or diaphysis
and two extremities,
each called epiphysis
long bones
typified by the carpal bones
of the wrist and the tarsal
bones of the ankle
short bones
consist of two plates of
compact tissues enclosing a
layer of spongy bone
flat bones
bones according to development
bones formed by intramembranous ossification, bones formed by endochondral ossification
how many bones in adult body
206 bones
12 pair of ribs; true ribs, ___; false ribs; ___
1-7, 8-12
dividing bone
suture
floating bone
hyoid bonen(sa may baba)
5 general parts of vertebral column
cervical curvature c1-c7
thoracic curvature t1, t12
lumbar curvature l1, l5
sacrum 5
coccyx 4
head of bone
epiphysis
body of bone
diaphysis
area of union between 2 or more bones
joints arthroses
fibrous connective tissue holds
the bones together
fibrous joints synarthroses
cartilage holds the bones
together; slightly moveable
cartilagenous joints (amphiarthroses)
a cavity with fluid found
between bones; Freely moveable
synovial fluid; diarthroses
