Tissue Quiz

Question 1

4 major types of tissues

Answer 1

Epithelial tissue
Connective tissue
Muscular tissue
Nervous tissue

Question 2

Epithelial tissue
LOCATION AND FUNCTION

Answer 2

locations- body covering, lining.
Glandular tissue
Functions- protection, absorption, filtration, secretion

Question 3

Cell shapes and epithelial types

Answer 3

Epithelium- simple, pseudoostratified columnar, stratified
Cell shapes- squamous, cuboidal, columnar

Question 4

4 types of epithelia with only one layer on cells

Answer 4

Simple squamous
Simple cuboidal
Simple columnar
Pseudostratified columnar

Question 5

Nervous tissue 1

Answer 5

Communications by electrical and chemical signals

Consist of neurons (nerve cells)

Neuroglia (glial)

Question 6

Connective tissue

Answer 6

Loose fibrous connective tiss
Dense fibrous connective tiss
Adipose tissue
Bone
Cartilage
Blood
Lymphatic

Question 7

Areolar tissue

Answer 7

Loosely organized fibers
Abundant blood vessels
Underlies epithelial
In membranes
Between muscles
Pass way for nerves + blood vessels

Question 8

Reticular tissue

Answer 8

Mesh of fibers and fibroblasts
Supportive storms for lymphatic organs
Found in nodes, spleen, bone, and thymus

Question 9

Dense regular connective tissue

Answer 9

Packed parallel collagen fibers
Compressed fibroblast nuclei
Elastic tissue forms wavy sheets in some locations
Tendons attach muscles to bones and ligaments hold bones tgther

Question 10

adipose tissue

Answer 10

Empty looking cells (thin margins)
Nucleus pressed against cell membrane
Energy storage, Insulation, cushioning
Subcutaneous fat and organ packing
Brown fat juveniles produces heat

Question 11

Compact bone

Answer 11

Arranged in cylinders that surrounded central canals that run longitudinally through shafts of long bones
Blood vessels and nerves travel through central canal
Bone matrix in concentric lamellae
Onion layers around each central canal

Question 12

What is BLOOD

Answer 12

Types of connective tissue
Contains loving and non loving components
PURPOSE- transports nutrients and waste throughout body

Question 13

Formed elements

Answer 13

Leukocytes & thrombocytes
Erythrocytes

Question 14

Blood cells

Answer 14

Make up of 45% of volume
Types-
Erythrocytes- red blood cells- RBC
Leukocytes-white blood cells WBC
Platelets- not actually cells clotting factors)

Question 15

Plasma

Answer 15

Liquid part of blood
Contains plasma proteins-
Albumin- maintains osmotic pressure
Fibrinogen and globulin- clotting factors
Water ( liquid solvent)
Salts (maintain osmotic pressure)
Nutrients carried in blood

Question 16

Erythrocytes (RBC’s)

Answer 16

Purpose- carry oxygen to tissues
Hemoglogin- types of protein
Contains iron which binds with oxygen
Concentration determine availability of oxygen to cells

Question 17

Heme

Answer 17

Oxygen bind to gene on the hemoglobin molecule

Question 18

Leukocytes (WBC’s)

Answer 18

Purpose- defend against infectious agents ( bacteria, viruses, parasites)
Mechanisms-
DIAPEDESIS-Ability to move across blood vessels
Use circulatory system as highway
POSITIVE CHEMOTAXIS- can locate area of damage/ infection by responding to released immune bacterial chemicals

Question 19

Types of leukocytes

Answer 19

Neutrophil- active phagocyte and 1st responder
Increase in # during infection
Eosinophil- kill larger parasites+allergins
Basophils- cause infection response
Release histamine> dilating blood vessels

Question 20

Lymphocytes

Answer 20

B- produce antibodies
T- respond to antibodies on foreign tissue

Question 21

Monocytes

Answer 21

Largest + most active phagocytes
Used for chronic, widespread infections

Question 22

Platelets

Answer 22

Fragments of multinuxleate cells
Irregular shape (necessary in clotting)
Initiate clotting cascade by clinging to broken vessel walls
