QUIZ 2.1 Flashcards
Groups of cells similar in structures and fuctions
Tissues
is a type of animal tissue that forms the inner and
outer lining of organs, the covering in surfaces, and the primary glandular tissue of the body.
Epithelial tissue or epithelium
one layer flat, scalelike
SSE
one layer cubeshaped
SCBE
one layer elongated or columnshape
SCE
one layer elongated or columnshaped (Nose)
PSCE
more than one layer flat, scalelike
SSE
more than one layer cubeshaped
SCBE
more than
one
layer
elongated
or columnshaped
SCLE
● layers of a very
hard matrix with
calcium salts and
collagen fibers
● consists of bone
cells called
lacunae
Bone
● more flexible
matrix than
bone
● cartilage cells
called ___
Cartilage, chondrocytes
● Matrix is
predominantly
made up of
collagen fibers
and has lesser
cells.
● This is a
fibroblast or a
fiber-forming cell.
DCT
● Matrix
contains
more cells
and lesser
fibers than
dense
connective
tissue so it is
softer.
LCT
● plasma
● Cellular components
consist of blood
cells.
● with fibers that are
only visible during
clotting because
they are made up of
soluble proteins
Blood
differ in their general
structure but more or less perform the same function,
i.e., to elicit movement
Muscular Tissues
long, cylindrical,
striated (with
visible stripes),
and
multinucleated
(with more than
one nucleus)
Skeletal muscle
made up of
nonstriated,
uninucleated,
and spindleshaped
(have
pointed ends)
cells.
Smooth muscle
uninucleated
(one nucleus)
and has
striations
has intercalated
disks
Cardiac Muscle
the basic unit of the nervous system, consists
of structures that can conduct electrochemical signals
as a form of information
Neuron
Neurons may be classified based from their number of
cellular processes.
Multipolar, Bipolar, (Pseudo) Unipolar
These are starshaped
cells that
support and control
the chemical
environment around
the neurons.
These are the most
abundant glial cell in
the CNS.
Astrocytes
These are ovoid cells
in the CNS that can
transform into a
phagocytic
macrophage to clean
neuronal debris and
wastes.
Microglial cells
These are ciliated
cells that line the
central cavities of the
brain and the spinal
cord and form a fairly
permeable
membrane between
the cavities with
cerebrospinal fluid
and the tissues of
CNS.
Ependymal cells
These are
responsible for the
production of the
myelin sheath.
Oligodendrocytes
They surround the
cell body of a neuron.
Satellite cells
They surround all the
nerve fibers and
produce myelin
sheath similar to the
oligodendrocytes.
Schwann cells
is composed of tightly packed cells that
cover, line, and protect the body part. It can be classified
based on cell arrangement
Epithelial tissue
is made up of cells and an extracellular
matrix that connects, protects, and supports body parts.
Connective tissue
is composed of highly specialized muscle
cells that contract to produce movement.
Muscular tissue
is made up of neurons that receive and
conduct electrochemical signals and supporting cells
Nervous Tissue
