Question 1

Gland

Answer 1

Cluster of epithelial cells that secretes a substance that functions outside the cell

Question 2

Exocrine gland

Answer 2

Gland that secrets milk sweat saliva oil or some other substance through a duct
Deliver their secretion onto and internal or external surface

Question 3

Endocrine gland

Answer 3

Ductless gland that secretes hormones into a body fluid

Hormones enter the bloodstream which then distributed them throughout the body.

Question 4

Connective tissue

Answer 4

Animal tissue with extensive extracellular matrix
Bind support strengthen protect and insulate other tissue
Range from soft connective tissues to specialized bone tissue cartilage adipose tissue and blood

Question 5

Fibroblast

Answer 5

Main cell type in soft connective tissue
Secretes collagen and other components ( such as polysaccharides) or extracellular matrix
The extracellular matrix sounds and supports the tissue cells

Question 6

Loose connective tissue

Answer 6

Connective tissue with relatively few fibroblast and fivers scattered in its matrix
The most commonly type in vertebrates
Hold organs and epithelia in place
Store fluid

Question 7

Dense connective tissue

Answer 7

Connective tissue with many fibroblast and collagen fibers in its matrix
May have a regular or irregular arrangement

Question 8

Cartilage

Answer 8

Connective tissue with cells surrounded by a rubbery matrix of glycoproteins and collagen fibers
Cushion joints; supports ears and nose

Question 9

Bone tissue

Answer 9

Connective tissue with cells surrounded by a calcium-hardened matrix
Supports and moves the body; produces blood cells

Question 10

Adipose tissue

Answer 10

Connective tissue with fat storing cells

Stores energy, cushions and protects, insulates

Question 11

Blood

Answer 11

Fluid connective tissue; a transport medium
Cells and platelets form inside bones; transport oxygen, help blood clot, have immune functions
Plasma, the fluid portion of blood, transport gases, nutrients, hormones, water, wastes

Question 12

Skeletal muscle tissue

Answer 12

Attaches to bone to move body parts - voluntary , striated , multiple nuclei

Question 13

Cardiac muscle tissue

Answer 13

Makes up the heart wall- involuntary , striated , single nuclei

Question 14

Smooth muscle tissue

Answer 14

Lines blood vessels and other hollow organs - involuntary , not striated, single nuclei

Question 15

Muscle tissue facts

Answer 15

Cells of muscle tissues contact in response to signals from nervous tissue and help move the body or parts of it
Voluntary vs involuntary

Question 16

Nervous tissue

Answer 16

Allows body to detect and respond to internal and external changes
Detects stimuli
Integrates information
Controls actions of muscles and glands

Question 17

Neurons

Answer 17

Transmit electrical signals along the plasma membrane

Communicate with other cells through chemical signals

Question 18

Neuroglia

Answer 18

Support and protect the neurons

Question 19

Four types of vertebrates and function

Answer 19

Epithelial tissue : covers body surfaces and line internal cavities
Connective tissue : hold body parts together and provide structural support
Muscle tissue : move the body and its parts
Nervous tissues : detect stimuli and relay information
