cells.
● This is a
fibroblast or a
fiber-forming cell.

Answer 12

DCT

Question 13

● Matrix
contains
more cells
and lesser
fibers than
dense
connective
tissue so it is
softer.

● Cellular components
consist of blood
cells.
● with fibers that are
only visible during
clotting because
they are made up of
soluble proteins

Question 19

the basic unit of the nervous system, consists
of structures that can conduct electrochemical signals
as a form of information

Answer 19

Neuron

Question 20

Neurons may be classified based from their number of
cellular processes.

Answer 20

Multipolar, Bipolar, (Pseudo) Unipolar

Question 21

These are starshaped
cells that
support and control
the chemical
environment around
the neurons.
These are the most
abundant glial cell in
the CNS.

Answer 21

Astrocytes

Question 22

These are ovoid cells
in the CNS that can
transform into a
phagocytic
macrophage to clean
neuronal debris and
wastes.

Answer 22

Microglial cells

Question 23

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.

Answer 23

Ependymal cells

These are
responsible for the
production of the
myelin sheath.

Answer 24

Oligodendrocytes

Question 25

They surround the cell body of a neuron.

Answer 25

Satellite cells

Question 26

They surround all the nerve fibers and produce myelin sheath similar to the oligodendrocytes.
