ANPH 1001 Chapter 5 Tissues Exam
Questions and Answers Graded A+
Classify epithelial tissue based on shape and arrangement and give examples. -
Correct answer-Shape
Squamous: Cells are flat and slightly irregular in shape, serve as a protective layer.
Cuboidal: Cells look like small cubes. Function can be secretion, protection, or
absorption.
Columnar: Tall and Rectangular looking, often have the nucleus towards the
bottom of the cell. Many are ciliated.
Arrangement
Simple: One cell layer thick.
Stratified: Several Cell layers thick.
Pseudostratified: Appears to consist of several layers due to nuclei variously
positioned in the cell, but really all cells extend from the basement membrane to
the outer/free surface of the cells. Usually seen with Columnar cells.

,Transitional Epithelium: Consists of several layers of closely packed, flexible,
easily stretched cells. When surfaces of cells are stretched the cells appear
Squamous. When tissue is relaxed the layers of cells look ragged like saw teeth.
Name the types of glands in the body and give examples. - Correct answer-
Exocrine Glands: Simple Exocrine: (have single duct (sweat glands, most glands of
digestive tract, sebaceous glands) Compound Exocrine: (Made of several
component lobules with ducts that join other ducts (branching) Examples:
Mammary glands, Large Salivary Glands)
Endocrine Glands: (Ductless, secrete hormones) Thyroid, Pituitary
Goblet Cells: (Unicellular glands, secrete mucus) Interspaced among the epithelial
cells that make up mucous membranes.
Name the functions of connective tissue. - Correct answer-Allows movement, and
provides support for other types of tissue.
Compare epithelial tissue with connective tissue in terms of cell arrangement and
interstitial materials. - Correct answer-Intersitial Materials: Epithelial tissue is
made of cells closely packed together with very little intercellular material.
Connective tissue's cells have lots of intercellular material called matrix between
them. This matrix is fluid containing reticular fibers, collagen fibers, fiboblast

,cells, and elastic fibers. The amounts of each thing depends on the type of
connective tissue.
Arrangement: Epithelial cells are anchored to the basement membrane and have
four arrangements. Simple is one cell layer thick. Stratified is several layers of
cells thick. Pseudostratified looks like it is several layers thick, but all cells extend
from the basement membrane to the outer surface. Transitional is several layers of
closely packed, easily stretched cells. When stretch they look flat, when relaxed
they look saw-toothed. Connective tissue cells differ on arrangement depending on
what connective tissue it is.
Name the three major types of connective tissue and give examples. - Correct
answer-Loose Connective Tissue: It fills spaces between and penetrates into
organs. There are three types: Areolar (the most widely distributed, easily
stretched, resists tearing.), Adipose (fat stored in it's cells), Reticular (forms
frameworks).
Dense Connective Tissue: Two Types: Regular (the fibers lined in a specific
direction) which is found in Ligaments, Tendons, and Aponeuroses. As well as
Irregular (No specific alignment of fibers) which is found in muscle sheaths, the
dermis layer of skin, and outer coverings of body tubes like arteries. Joint Capsules
and Fascia also have Dense irregular connective tissue .

, Specialized Connective Tissue: A connective tissue that has a specialized function.
Cartilage, Bone, Dentin, Blood, Lymphoid Tissue, RE System, Synovial
Membranes.
List the functions of Connective Tissue. - Correct answer-1. Support: Bones
support other tissues of the body. We also find muscle, nerves, blood vessels, fat,
and skin. Cartilage supports our nose and forms most of the ear structure.
2. Nourishment: Blood carries nutrients to the cells in the body. Synovial
membranes in joint capsules nourish the cartilage found on top of bones.
3. Transportation: Blood moves gases, enzymes, and hormones to cells.
4. Connection: Tendons connect muscles to bone, ligaments connect bone to bone.
5. Movement: Muscles through tendons pull on bones, bones move our bodies
through our environment.
6. Protection: Bones protect vital organs, like the heart, lungs, brain, and spinal
cord. Blood cells, especially white blood cells protect us from foreign
microorganisms and tissue injury.
7. Insulation: Adipose tissue (fat) insulates us from excessive heat loss, and
excessive temperature rises.
