Chapter 4- Tissues

Question 1

Membrane

Answer 1

protective tissue surrounding internal organs, produces fluids

Question 2

4 major types of tissues

Answer 2

Epithelial, Muscle, Nervous, Connective

Question 3

Epithelial Tissue

Answer 3

Tightly packed cells, surrounds body surface (skin), lines body cavities (blood vesicles, intestinal tract), covers and lines

Question 4

Squamous

Answer 4

Flat

Question 5

Cuboidal

Answer 5

Cube shaped

Question 6

Columnar

Answer 6

Long, column shaped

Question 7

Stratified Layer

Answer 7

Simple: one layer
Stratified: two or more layers
Pseudo-stratified: looks like multiple layers, but is only one

Question 8

Basement Membrane

Answer 8

Thin layer of connective tissue that attaches to Epithelial Tissue to other tissues

Question 9

Muscle Tissue

Answer 9

Packed tightly, 3 types (skeletal, smooth, cardiac), can only contract (get shorter) and relax

Question 10

Skeletal

Answer 10

Bones, multiple nucleus, striations indicate relative strength, parallel grooves

Question 11

Smooth

Answer 11

No striations, not as strong as skeletal but NOT weak, involuntary movements

Question 12

Cardiac

Answer 12

Single nucleus, heart, is branched, cells are fused together

Question 13

Nervous Tissue

Answer 13

Involved in communication, tightly packed, Neurons make up a majority of the tissue, Cell Body contains organelles, Dendrites can generate an electrical charge (some), all can transmit impulses, Neurons associated with the senses can generate an electrical impulse

Question 14

Neuroglia

Answer 14

Number of Neurons, support and protection, some produce cerebrospinal fluid (inside the brain and spine)

Question 15

Internal Membranes/Serosa

Answer 15

Surrounds organs and produces fluid, fluid prevents friction and organ movement, Heart is surrounded by the Pericardial, Lungs are surrounded by the Pleura, Abdomino-pelvic (small and large intestines) is surrounded by the Peritoneum

Question 16

Mehinges

Answer 16

Surround the brain and spine, do not produce their own fluid, they trap fluid produced by neuroglia cells

Question 17

Connective Tissue

Answer 17

Cells are spaced apart, connects, Basement Membrane

Question 18

Matrix

Answer 18

Space between the cells in connective tissue, cells within the matrix make the substances within the matrix (proteins)

Question 19

Loose Connective Tissue

Answer 19

Contains white fibers (proteins, flexible), yellow fibers (elastic), adipose tissue (storage of fat, insulation, cushion)

Question 20

Fibrous

Answer 20

White fibers, yellow fibers, Collagenous fibers (stronger and more rigid), tendons and ligaments

Question 21

Cartilage

Answer 21

Solid, Flexible matrix, higher concentration of protein fibers, no direct blood supply (heals slowly)

Question 22

Bone

Answer 22

Solid, hard matrix, has all three types of fibers + calcium, living tissue, constantly being broken down and repaired, compact and spongy
