1

the study of tissues

histology

2

the four fundamental tissues are

epithelial
connective
muscle
nerve

3

Description of epithelial tissue

no intracellular space
apical basal structure
avascular
keratinized/nonkeratinized
lining of organs
superficial

4

Simple Squamous epithelium

filtering and diffusion
alveoli in the lungs

5

Simple Cuboidal epithelium

secrete and absorb
kidney tubules

6

Simple Columnar epithelium

absorption, secretion of mucous
digestive tract

7

Stratified squamous epithelium

nonkeratinized,
protects underlying tissues
mouth

8

Description of Connective:

large intracellular space
varies vascularity
deeper
nonliving extracellular matrix (withstand great tension and abuse)

9

types of connective tissue

blood
bone
cartilage
adipose
reticular connective tissue

10

Description of Nervous Tissue:

composed of neurons and connective tissue cells that are called NEUROGLIA

11

Description of Muscle Tissue

classifies as involuntary/ voluntary
contract or shorten

12

attach muscle to bone

tendons

13

sheetlike tendons, attach muscles to other muscles

aponeurosis

14

binds bones together at joints

ligaments

15

the basic unit of life and the building block of tissues and organs

cell

16

contains the DNA in the cell

nucleus

17

important in the synthesis of proteins

ribosomes

18

powerhouse of the cell

mitochondria

19

package and modifies

golgi apparatus

20

selective membrane, controls what goes in and out of the cell

plasma membrane

21

synthesize and stores proteins

smooth ER

22

membrane factory

rough ER

23

aid in cell division

centrioles

24

demolition crew

lysosomes

25

necessary for growth and repair, in this process, the DNA is duplicated and distributed evenly to two daughter cells

meiosis

26

is the special division that takes place in the gonads. the chromosome number is reduced from 46 to 23, so when the egg and sperm unite, the zygote will then have the correct number of chromosomes

mitosis
