Answer 1

Epithelial tissue or epithelium
Connective tissue
Muscle tissue
Nervous tissue

Question 2

purpose of:

Epithelial tissue

Answer 2

provides coverings and lining membranes for surfaces inside and outside the body for:
Protection of underlying structures

Secretion

Absorption

Question 3

purpose of:

Connective tissue

Answer 3

protect and support the body and its organs

provide bindings for the organs

Transport

Insulation

Question 4

purpose of:

Muscle tissue

Answer 4

produce motion by contracting

Question 5

purpose of:

Nervous tissue

Answer 5

to receive stimuli from both inside and outside the body and relay them to the brain, and to transmit impulses from the brain to other tissues of the body

Question 6

example of:

Epithelial tissue

Answer 6

glandular epithelium

Question 7

function of a gland

Answer 7

to secrete substances:
hormones
enzymes
perspiration
mucus

Question 8

two types of glands

Answer 8

Endocrine (ductless): secretes into bloodstream

Exocrine (ducted): secretes via a duct or directly onto a free surface

Question 9

examples of:

Connective tissue

Answer 9

Blood
Bone
Cartilage
Neuroglia

Question 10

example of:

Nervous tissue

Answer 10

nerve cells are called neurons and are supported by Neuroglia

Question 11

examples of:

Muscle tissue

Answer 11

Skeletal (voluntary) attached to the skeleton

Smooth (involuntary) found in digestive tract and blood vessels etc.

Cardiac (involuntary) found in the heart

Question 12

Epithelial tissue may be:

Answer 12

Simple: a single layer of cells

Stratified: several layers of cells

Question 13

examples of:

Simple Epithelium

Answer 13

Squamous (pavement) epithelium
Cuboidal epithelium
Columnar epithelium

Question 14

define:

Squamous epithelium

Answer 14

flattened cells fitting closely together, laying on a basement membrane. forming a thin and very smooth membrane across which diffusion occurs.

Question 15

define:

Cuboidal epithelium

Answer 15

cube shaped cells fitting closely together laying on a basement membrane. actively involved in secretion, absorption and/or excretion

Question 16

define:

Columnar epithelium

Answer 16

rectangular in shape, on a basement membrane. it has adaptations that make it well suited to a specific function.

Question 17

define:

Ciliated columnar epithelium

Answer 17

rectangular in shape, on a basement membrane. the epithelial cells have cilla on top

Question 18

examples of:

Stratified Epithelium

Answer 18

Stratified squamous epithelium

Transitional epithelium

Question 19

define:

Stratified squamous epithelium

Answer 19

composed of several layers of cells. the deepest layers are columnar and as the grow toward the surface the become flattened and are shed.

Question 20

define:

Transitional epithelium

Answer 20

this is composed of several layers of pear shaped cells. It lines several parts of the urinary tract including the bladder and allows for stretching as the bladder fills.

Question 21

Cells in connective tissue:

Answer 21

Fibroblasts
Fat cells
Macrophages
Leukocytes
Mast cells

Question 22

Two types of nervous tissue

Answer 22

Excitable cells (neurones) initiate, receive, conduct and transmit information

Non-excitable cells (glial cells) support the neurones

Question 23

muscle cells are:

Answer 23

specialised contractile cells

Question 24

systems

Answer 24

integumentary
muscular
skeletal
nervous
endocrine
lymphatic
cardiovascular
respiratory
digestive
urinary
reproductive
