2.Tissue And Body Cavities

Question 1

Epithelial tissue

Answer 1

Protects body may be secretory and absorbent

Question 2

Connective

Answer 2

Binds tissue together

Question 3

Muscle

Answer 3

Brings about movement

Question 4

Nervous tissue

Answer 4

Conveys nerve impulses from one area to another and coordinate response

Question 5

Simple

Answer 5

One cell thick endothelium

Question 6

Stratified

Answer 6

More then one layer thick endothelium

Question 7

Endothelium

Answer 7

Epithelium lining the structures such as inside of heart and blood vessesls

Question 8

How can the epithelium have more protection

Answer 8

Presence of protein keratin

Question 9

Squamous cells

Answer 9

Flattened in shape

Question 10

Cuboidal cells

Answer 10

Square or cube shaped

Question 11

Columnar cells

Answer 11

Column shaped

Question 12

Where and what would u find pseudostratified epithelium

Answer 12

Trachea

Appears to look multilayered because of irregular positioning

Question 13

Transitional epithelium

Answer 13

Specialised stratified epithelium found lining parts of urinary system and are capable of considerable distension and variation of internal pressure and are able to change shape according to circumstances

Question 14

Exocrine glands

Answer 14

System of ducts through which their secretory products are transported directly to the site where they will be used

Question 15

Endocrine glands

Answer 15

Do not have a duct system and their secretion are carried by blood to target organs which may distance away

Question 16

Connective tissue in order if increasing density

Answer 16

1) blood
2) haemopoietic tissue or loose connective tissue
3) areolar tissue or loose tissue
4) adipose or fatty tissue
5) fibrous connective tissue or dense connective tissue
6) cartilage
7) bone

Question 17

Haemopoetic tissue

Answer 17

Jelly-like connective tissue forms in bone marrow within long bones and responsible for formation of blood cells

Question 18

Areolar tissue

Answer 18

Most widely distributed type of connective tissue.
Contains collagen fibers with high tensile strength and elastic fibers which enable tissue to stretch and return to former shape.

Question 19

parietal endothelium

Answer 19

serous membrane which lines boundaries or side of cavity

Question 20

viseral endothelium

Answer 20

serous membrane which covers all the organs within the cavity

Question 21

thoracic cavity

Answer 21

contains heart, lungs, other associted structures. its sketeal walls are formed by the bony thoracic cage

Question 22

cranial thoracic inlet

Answer 22

eneternce to the thoraxic cavity and formed by first thoracic vertabra, first pair of ribs and manubrium.

Question 23

pleura

Answer 23

serous mebrane lining the thoracic cavity and covering the organs within

Question 24

parential pleura

Answer 24

lines inside of thoracic cavity but changes name according to wall it covers e.g diaphragmatic pleura

Question 25

pulmonary pleura

Answer 25

lungs themselves are covered in viseral pleura

Question 26

mediastinum

Answer 26

potential space formed by double layer of parential pleura that separates two pleural cavities.

Question 27

peritoneum

Answer 27

serous membrane which lines the internal surface if the abdominal cavity

Question 28

peritoneal cavity

Answer 28

potential space between the parential peritoneum that lines the abdominal walls and the visercal peritoneum that covers organs..

contains small volume of lubricating serous fluid (peritoneal fluid) allowing friction free movement of organs

Question 29

visercal peritoneum ( mesentray)

Answer 29

folds on itself to keep the organs separate, suspending the organs within the abdominal cavity and carrying the various vessels and nerves that serve the viscera.

Question 30

folds of mesentary

Answer 30

different names depending on their postion.
mesoduodenum= duodenum mestray
mesovarium= ovary

Question 31

omentum

Answer 31

mobile fold of peritoneum that contains a lacy network of fine vessels and fat and is divided into the greater omentum arising from the greater curvature of the stomach and lesser omentum rising from thr lesser curvature of stomach.
