6

3 Types of Depressions

1. Alveolus (Alveoli)
2. Fossa (Fossae)
3. Sulcus

7

Alveolus (Alveoli)

Deep pit/socket in maxillae or mandible
ex. where teeth are

8

Fossa (Fossae)

Flattened or shallow depression
ex. on pelvis

9

Sulcus

Narrow groove
ex. on Sphenoid bone

5 Types of Openings and Spaces

1. Canal
2. Fissure
3. Foramen (foramina)
4. Meatus
5. Sinus

21

Opening:
Passageway through a bone

22

Fissure

Opening:
Narrow
Slitlike opening through a bone

23

Foramen (foramina)

Opening:
Rounded passageway through a bone

24

Meatus

Opening:
Passageway through a bone

25

Sinus

Space:
Cavity or hollow space in a bone

26

Axial Skeleton

Bones along the central axis
Has 3 regions

27

3 Regions of the Axial skeleton

1. Skull
2. Vertebral column
3. Thoracic cage

28

Functions of the Axial skeleton

1. Framework to support and protect organs
2. Spongy bone located here - hemopoietic

29

Appendicular Skeleton

Bones of the limbs and the girdles

30

2 Girdles

1. Pectoral
2. Pelvic

31

Pectoral girdle function

Holds upper limbs in place

32

Pelvic girdle function

Holds lower limbs in place

33

Cranial bones

Rounded bones of skull
Encase the BRAIN

34

Facial bones

Bones of skull that aren't cranial
Make up the face
Protect entrance to digestive and respiratory systems

35

Abduction

Movement of a bone away from the midline

36

Adduction

Movement of a bone toward the midline

37

Circumduction

A continuous movement that combines flexion, extension, abduction and adduction in succession

38

The 3 types of movement that can occur between the vertebraee in the cerical and lumbar regions of the vertbral column

Lateral Flexion
Spinal Extension
Spinal Fexion

39

______ rotation turns the anterior surface of the femur or humerus medially

Medial

40

_____ is the extention of a joint beyond 180 degress

Hyperextension

41

_____ occurs when the forearm rotates laterally so the palm faces anteriorly or superiorly

Supination

42

Heel is lower than toes

Dorsiflexion

43

Heel is higher than toes

Plantar flexion

44
