Flashcards in Axial Skeleton + Body Cavities Deck (42)
1

Bones

Structure, movement, nutrient storage, hematopoetic blood stem cells. Calcium and phosphate.

2

Joint

How bones interact with each other, functional points for movement.

3

Axial skeleton

Skull, vertebrae, ribs

4

Skull

Everything you can see on the exterior (for now).

5

Vertebrae

5 groups of vert. Cervical, thoracic, lumbar, sacral, coccyx. Each region has a specific number relating to somite loosely.

6

Primary curves

Thoracic and sacral/coccyx. Typhosus

7

Secondary Curves

Lumbar - lordosis and cervical. Curves exist for balance and creating an even weight distribution.

8

Pedacles

Columns that connect body to arch (Vertebrae)

9

Vertebral body/arch

Prevent twisting too far (protect spinal cord and spinal nerves), among others.

10

Intervertebral foramen

Created by two bones coming together (not rare, but not as common as a regular bone). Spinal nerves will exit/enter vertebral canal here.

11

Transverse Foramen

Cervical vert. Vertebral artery and vein, plus *sympathetic nerves*

12

Vertebral arteries

Posterior blood supply to the brain. Anterior is carotid.

13

Ribs are higher

posteriorly. Curved inferiorly and anteriorly. During inspiration they move superiorly and laterally.

14

Costal cartilage

Strong rigidity to be a protective cage while providing flexibility for breathing.

15

Nucleolus pulposis

Center anterior core of intervertebral disc. Notochord gives rise to this structure.

16

Scleratome

Gives rise to vertebrae, somite differentiates into scleratome.

17

Know slide 9

pay attention to costal groove - allows you to tell superior to inferior (this is always inferior).

18

A.V.N.M.

Artery, vein, nerve, muscle.

19

Joint capsule

Dense fibrous connective tissue. Red lining cavity is Synovial membrane (where you find cells producing synovial fluid).

20

Synovial fluid

Nourish and cushion.

21

Atlantoaxial joint

C1 and C2 joint. Synovial joint at dens of C2 against anterior arch of C1. This allows for head rotation.

22

Atlanto-occipital/lots of cervical vert

Nodding.

23

Hyaline cartilage

Synovial joints.

24

Cartilagenous solid joints

Very slight motion associated with them, if any. Often immobile.

25

Fibrous solid joints

Sutures (between bones of skull). Gomphosis is like this.

26

Syndesmosis

Interosseous membrane

27

Diaphragm

separates Abdominopelvic cavity and Thoracic cavity. Comes down to T12 posteriorly, anteriorly it only goes down to the sternum base.

28

Breathing

contraction of diaphragm/relaxation of abs = inhale. Relax of diaphragm/contract abs = exhale. Thoracic and abdominopelvic cavity working together. Ribs move up and out and take sternum with it.

29

Abdominopelvic cavity

bony landmarks can define and distinguish the structures. Sacral/coccyx vert and lumbar vert.

30

valsalva maneauver.

Increasing intra-abdominal pressure is often referred to as the valsalva maneauver. The valsalva is accomplished by attempting to forcibly exhales against a closed airway.

31

Micturation

Peeing.

32

Mesothelium

Lines cavity

33

intraperitoneal structures

intraperitoneal structures = suspended in mesenteries

34

retroperitoneal structures

retroperitoneal structures = lie between the parietal peritoneum and the abdominal wall

35


Parietal peritoneum

lines the abdominal wall

36


Visceral peritoneum

covers the suspended organs (viscera)

37

Thoracic cavity

Packed tightly - parietal pleura, thin small barely identifiable pleural cavity between this and visceral pleura. Visceral pleura follows shape of organs. Tiny space is filled with serous fluid for reducing friction.

38

Fluids in body

Reducing friction or digestive process, blood, nutrient delivery.

39

Mediastinum

Heart and trachea here.

40

Cranial cavity

Lined with meninges -3 of them. Dura, arachnoid, pia mater. Protect brain.

41

nasal cavities
nasal sinuses
oral cavity
orbit= eye socket
middle & inner ear cavities

Anterior extent is open.
