Flashcards in Chapter 3 Deck (38):
1

Functions of epithelia tissue

Provide physical protection,
control permeability, provide sensation,
produce specialized secretions

2

Epithelia specializations

1. Lateral cell surfaces
2. Maintain close cell-to-cell contact and form covering sheets
3. Epithelium structurally and functionally polarized to increase efficiency of absorption and transport

3

Simple squamous epithelium

Location:heart, blood vessels
Function: reduces friction & absorbs and secrets materials

4

Stratified squamous epithelium

Location: skin surface, lining of mouth, esophagus anis and virgins
Function: protect against abrasion and chemicals

5

Simple cuboidal epithelium

Location: thyroid glands, ducts kidney
Function:secretion, absorption protection

6

Stratified cuboidal epithelium

Location: Ducts of sweat glands (rare)
Function: secretion, absorption, protection

7

Simple columnar epithelium

Location:lining of stomach intestines, uterine tubes and collection of ducts of kidneys
Function: psa

8

Stratified columnar epithelium

Location: pharynx, epiglottis, mammary glands, salivary glands anus
Function: ps

9

Pseudo stratified ciliates columnar epithelium

Location:lining of nasal cavity, broachi and portions of male reproductive organs
Function: PS

10

Transitional epithelium

Location: urinary bladder, pelvis, ureters
Function: permitted expansion and recoil

11

Collagen fibers

It provides strength and cushioning to many different areas of the body, including the skin. More specifically, collagen is found in our various types of connective tissue such as cartilage, tendons, bones, and ligaments

12

Elastic fibers

found in extracellular matrix of connective tissue and produced by fibroblasts and smooth muscle cells in arteries. These fibers can stretch up to 1.5 times their length, and snap back to their original length when relaxed.

13

Reticular fiber

connective tissue composed of type III collagen secreted by reticular cells. Reticular fibers crosslink to form a fine meshwork

14

White blood cell apart of the immune system

Mast cell

15

White blood cells that eat anything that's not healthy to the body ex: cancer cells

Macrophages

16


ANATOMY
a cavity or depression, especially in bone.
Feedback

Lacunae

17

Functional unit of most compact bones

Osteon

18

Star shaped bone cell found most in mature bone tissue

Osteocytes

19

Main tissue component of the brain and spinal cord

Nervous tissue

20

cells found in cartilage connective tissue. They are the only cells located in cartilage, they produce and maintain the cartilage matrix,

Chondrocyte

21

Connects the two parts of the spinal cords

Central canal

22

many lamellae very close to one another, with open space between. Aside from respiratory organs

Lamelle

23

Small canal found in bones

Caniculi

24

Holds organs into place connect epithelia tissue to other underlying tissues commonly found in vertebrates

Loose Areolar tissue

25

Term for loose connective tissue composed of adipocytes. Its main role is to store energy in the form of fat, although it also cushions and insulates the body.

Adipose tissues

26

forms a scaffolding for other cells in several organs, such as lymph nodes and bone marrow.

Reticular tissue

27

provides connection between different tissues in the human body. Found in tendons and ligaments

Dense regular tissue

28

fibers that are not arranged in parallel bundles found around muscle and organs dermis

Dense irregular tissue

29

A type of connective tissue consisting mainly of elastic fibers and found in the walls of arteries, dermis of the skin, and certain ligaments and tendons.

Elastic tissue

30

makes up the embryonic skeleton. It persists in human adults at the ends of bones in free-moving joints as articular cartilage, at the ends of the ribs, and in the nose, larynx, trachea, and bronchi. tissue provides smooth surfaces, enabling tissues to move/slide easily over each other

Hyaline cartilage

31

great flexibility so that it is able to withstand repeated bending. The chondrocytes lie between the fibres. It is found in the epiglottis (part of the larynx),the pinnae (the external ear flaps of many mammals).

Elastic cartilage

32

found in the pubic symphysis, the anulus
Function: flexibility and toughness

Fibrous cartilage

33

cell showing minimal cytoplasm, limited amounts of rough endoplasmic reticulum and lacks biochemical evidence of protein synthesis.

Fibrocyte

34

a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.[1]

Blood

35

voluntary' control of the somatic nervous system. are attached to bones by bundles of collagen fibers known as tendons.

Skeletal muscle

36

is an involuntary, striated muscle that is found in the walls and histological foundation of the heart,

Cardiac muscle

37

microscopic identifying features of cardiac muscle. Connect heart muscle cells so it can function as a whole

Intercalated discs

38

contracts slowly and automatically. It constitutes much of the musculature of internal organs and the digestive system. The stomach

Smooth muscle
