Orthopedic Basic Sciences

Front 1

Epitehlium primarily occurs either on the outside of the body or as a lining of those cavities of the body that communicate with the exterior.

True or False

Back 1

True

Front 2

What are the general functions of epithelial tissue?

Back 2

Protection, absorption, and secretion

Front 3

Define Fibrous Connective Tissue:

Back 3

Tissue with spaces between the cells that are occupied by numerous fibers that makes the tissue tough and capable of withstanding distortions and strains.

Front 4

What is the loosely wooven (loose connective tissue) that is deep to the skin?

Back 4

A subcutaneous layer called the superficial fascia. To varying extents there will be modified tissue called Adipose tissue.

Front 5

What are the 2 specialized types of epithelium found lining closed caviies within the body?

Back 5

Mesothelium and Endothelium

Front 6

The cells of the body represent the living portion of the organism, while the intercellular substance represents the nonliving material and owes its existence to the activities of the cells.

True or False?

Back 6

True

Front 7

Collagen Fibers are essentially non elastic, when they occur in places where some deformation must be possible, how are the fibers arranged?

Back 7

In wavy bundles that allow movement until the slack of those bundles is taken up.

Front 8

Most biologic tissue is either:

Back 8

Porous or composite material

Front 9

Define Mesothelium:

Back 9

a single-layered squamous epithelium that lines the 4 great cavities of the trunk. Namely, the two pleural cavities surrounding the lungs, the pericardial cavity surrounding the abdominal viscera

Front 10

Various types of tissue are interwoven to form more complex anatomical and functional units known as:

Back 10

Organs or organ systems

Front 11

Fibrous Connective Tissue is the most pervasive type of connective tissue in the body

True or False

Back 11

True

Front 12

When normal connective tissue is in the form of enveloping sheaths it is known as:

Back 12

Fascia

Front 13

Define Endothelium:

Back 13

Essentially similar mesothelium in appearance, forms the inner lining of the heart, of all the blood vessels, and of the lymphatics.

Front 14

What are the basic types of epithelium?

Back 14

Simple - a single-layered
sheet of cells

Stratified - a multi-layered
sheet of cells

Glands - tubular out growth from such sheets

Front 15

Collagen tissue with or without elastic fibers is the most wide spread of all tisses. It permeates and surrounds practically all the tissues of the body.

True or False

Back 15

True

Front 16

Orthtopedic Surgery is the branch of medicine concerned with:

Back 16

Restoring and preserving the normal function of the musculoskeletal system.

Front 17

Define Connective Tissue:

Back 17

Connective Tissue has cells that are more or less widely dispersed ad separated from each other by nonliving intracellular material.

Front 18

Cells that occur in groups with component parts some what similar in appearance and function are known as:

Back 18

tissues

Front 19

Define Elastic Fibers:

Back 19

the fibers are elastic and may be stretched and when tension is relaxed, they shorten again.

Front 20

Subctaneous tissue is called the:

Back 20

Superficial Fascia

Front 21

What is the most common type of fiber found in connective tissue?

Back 21

Collagen Fiber

Front 22

Epithelial tissue occurs most commonly in sheets but is not adapted to cover other tissues.

True or False?

Back 22

False

It is adapted especially for covering other tissues.

Front 23

Define Fibroblasts:

Back 23

Cells that are responsible for the formation and repair of connective tissue fibers.

Front 24

Bone has mechanical properties that are influenced markedly by the degree of porosity, defined as the degree of volume that is void in the material. True or False?

Back 24

True,

for instance the compressive strength of osteoporotic bone, which has increased porosity , is markedly decreased in comparison with the compressive strength of normal bone.

Front 25

The Endomysium binds muscle fibers loosely together and it also binds one end of the Muscle Fiber to another or to a ligament

True or False?

Back 25

False

It will bind one end of a muscle fiber to another or to a Tendon.

Front 26

Individual muscles are surrounded by a thin fascia called the:

Back 26

Perimysium

Front 27

What are Myofibrils?

Back 27

The contractile elements of muscle fibers

Front 28

Describe the Dermis:

Back 28

The connective tissue underlying the skin and composed of densely matted fibers running in all directions. Composed mainly of collagen fibers but there are also some elastic fibers to give the skin some resiliency.

Front 29

Closely packed longitudinally arranged myofibrils present with alternating light and dark areas

True or False

Back 29

True

Front 30

Tissue deep to the superficial fascia and is very well developed is termed the:

Back 30

Deep Fascia

Front 31

A delicate layer of connective tissue directly out side the Sarcolemma is the:

Back 31

Endomysium

Front 32

Connective tissue fibers of a fascia within a plane run in many directions and appear interwooven. What is different from fascia compared to tendons and ligaments?

Back 32

The connective tissue fibers run roughly parallel to one another and are closely packed to form definite cords or bands, specially adapted to resist movement in one direction.

Front 33

The individual cells of the skeletal muscle which is very threadlike is termed:

Back 33

Muscle Fiber

Front 34

Fluid with in the connective tissue allows for movement of one muscle upon another.
