Histology

Question 4

This subject involves all aspects of tissue biology, with the focus on how cells’ structure and arrangement optimize functions specific to each organ.

Answer 4

Histology

Question 5

A ______ is a group of cells with interrelated function, not just a group of cells.

Answer 5

tissue

Question 6

● _____ in the tissue do not need to be the same type, or
same morphology.

Answer 6

Cells

Question 7

Since _____ are made up of cells, you can never understand the characteristics of a _____ without understanding the characteristics of its individual cells.

Answer 7

tissues

Question 8

The human body is organized at different levels, starting with the cell. ____ are organized into tissues, and _____ form organs. _____ are organized into organ systems such as the skeletal and muscular systems

Answer 8

Cells
tissues
Organs

Question 9

Answer 9

Muscle tissue
Epithelial tissue
Nervous tissue
Connective tissue

Question 10

cells that supports neurons or nerve cells

Answer 10

glial cells

Question 11

the cell of epithelial tissue

Answer 11

epithelial cell

Question 12

the cell of connective tissue

Answer 12

fibroblasts

Question 13

cell of muscle tissue

Answer 13

muscle cell - myocytes

Question 14

cells of nervous tissue

Answer 14

neurons and glial cells

Question 15

(tissue) to provide protection, and functions for absorption and secretion.

Answer 15

Epithelial tissue

Question 16

Epithelial tissue protects the stomach from what?

Answer 16

HCl (pH-1)

Question 17

are a type of intestinal mucosal epithelial cell, the primary function of ______ is to synthesize and secrete mucus. These mucins help neutralize the acids produced by the stomach.

Answer 17

Goblet cells

Question 18

T or F|Epithelial tissues are vascular.

Answer 18

FALSE - they are AVASCULAR (no blood vessels bcs they are tightly packed thus there is no space for blood vessels. )

Question 19

THE PRINCIPAL FUNCTIONS OF EPITHELIAL TISSUES
INCLUDE THE FOLLOWING:

Answer 19

a. Covering, lining, and protecting surfaces (eg.
epidermis).
b. Absorption (eg. the intestinal lining).
c. Secretion (eg. parenchymal cells of glands).

Question 20

If the epithelial tissue in the stomach is avascular, how can it get its oxygen and blood supply?

Answer 20

connective tissue - shares blood
supply and oxygen to the tightly packed epithelial tissue.

Question 21

provides a matrix that supports and
physically connects other tissues and cells together to form the organs of the
body

Answer 21

Connective tissue

Question 22

The interstitial fluid of _________ gives metabolic support to cells as the medium for diffusion nutrients and waste products.

Answer 22

connective tissue

Question 23

Epithelial Tissue and connective tissue are lovers.
________ is there to protect the connective tissue, while the ________ will always be there to keep the epithelial tissue alive.

Answer 23

Epithelial Tissue
connective tissue

Question 24

are responsible for connecting the epithelial tissue to the muscle tissue

Answer 24

Connective tissues

Question 25

provide movement of tissue, since it is
composed of elongated cells specialized for contraction.

Answer 25

Muscles

Question 26

contains bundles of very
long, multinucleated cells with
cross-striations.

Their contraction is quick, forceful, and usually under voluntary control.

Answer 26

Skeletal muscle

Question 27

also has cross-striations and is composed of elongated, often branched
cells bound to one another at structures called intercalated discs that are unique to it.

Contraction is involuntary, vigorous, and rhythmic.

Answer 27

Cardiac muscle

Question 28

consists of collections of fusiform cells that lack striations and have slow, involuntary contractions.

Answer 28

Smooth muscle

Question 29

In all types of muscle, ______ is caused by the sliding interaction of thick myosin filaments along thin actin filaments.

The forces necessary for sliding are generated by other proteins affecting the weak interactions in the
bridges between actin and myosin.

Answer 29

contraction

Question 30

provides sensation, control and
information processing

Answer 30

Nervous tissue

Question 31

Composed of cells with long, fine processes specialized to receive,
generate, and transmit nerve impulses.

Answer 31

Nervous tissue

Question 32

develops in the early embryo when the
dorsal ectoderm neural plate folds lengthwise to form the neural tube, the precursor of the CNS, and releases neural crest cells, precursors for much of the PNS.

Answer 32

Nervous tissue

Question 33

made up of the brain and spinal cord

Answer 33

CNS - Central Nervous System

Question 34

the part of your nervous system that lies outside your brain and spinal cord.

Answer 34
