Masseter


A, O, I

Named for

A - elevate the mandible (temporomanibular joint); may assist to protract the mandible (TM joint)

O - zygomatic arch

I - angle of the ramus of mandible

Named for it's action

2

Temporalis

A, O, I

Named for

A - elevate the mandible (TM joint); retract the mandible (TM) joint

O - temporal fossa and fascia (frontal, temporal & parietal bones)

I - coronoid process and anterior edge of ramus of the mandible


Named for location

3

Description

- 80 bones

- lie along the longitudinal axis

- skull, hyoid, vertebrae, ribs, sternum, ear ossicles

Appendicular skeleton

Description

- 126 bones

- upper and lower limbs and pelvic and pictorial girdles

5

Skull

Description

8 cranial bones

Protect brain and ear ossicles

- muscle attachment for jaw, neck and fascial muscles

13

Tissue defined

Groups of similar cells working together

4 types - CMEN

14

Epithelial tissue

Description

- specializes in moving substances in and out of the body
- covers and protects
- lines the body cavity
- forms glands

15

Connective tissue

Description

- specialized to support the body and its parts
- connects and holds body parts together
- transports substances through the body
- protects from foreign invaders

16

Muscle tissue
Description

- specializes in contraction
- produces movement

17

Nervous

Description

- specializes in communication
- integrates activities
- generates messages to coordinate function

17

Principles for naming epithelial tissue

Shape
- squamous
- cuboidal
- columnar

Layers
- simple
- stratified

18

Two types of tissue that make up our skin

Epithelial
Connective

19

Stratified squamous epithelium

2 types

Keratinized

Non-keratinized

20

Keratinized

Description

Cells contain the protein keratin
The keratin protein repels water (water proofing)
Found in the skin

21

Non-keratinized

Cells do not contain keratin
Lines the: vagina, mouth and esophagus
Free moist surfaces
Still serves as a protective layer

22

Connective tissue

3 types

Fibrous
Fluid
Skeletal

23

Connective tissue

General

One of the most widespread tissues in the body

Found in and around almost every organ in the body

24

Connective tissue named for

Structural characteristics

Intercellular material

26

Connective tissue consists of 2 things

Cells

Extra-cellular matrix

27

Cells

Surrounded by matrix

28

Matrix is made up of two things

Ground substance

Fibers

29

Matrix

Ground substance

- gel
- semi-hard substance
- hard
- liquid

30

Matrix

Fibers

- collagen
- elastin
- reticulin
