Respiratory System Part 2 Flashcards
1
Q
Functions of the Vertebral Column
A
- protects spinal cord
- supports the torso
- provides points for muscle attachment
- absorbs and cushions the shock and stress transmitted during walking and running
- joints for inter-vertebral motion
2
Q
C1-C7
A
Cervical Vertebrae
3
Q
T1-T12
A
Thoracic Vertebrae
4
Q
L1-L5
A
Lumbar Vertebrae
5
Q
4-5 Vertebrae
A
Sacral
6
Q
Vestigial Tail Section
A
Coccyx
7
Q
Corpus
A
- BODY of the vertebrae
- weight bearing
8
Q
Foramen
A
- allows nerve and vascular passage
- an actual hole
9
Q
Spinous Process
A
- for attachment of muscles and ligaments
- protective function as well
10
Q
Transverse Process
A
- horizontal
- also point of attachment for ribs
11
Q
3 types of vertebrae
A
- Cervical
- Thoracic
- Lumbar
- IDed a letter to designate type (C, L, T)
- IDed a number to indicate position (1,2..10)
12
Q
Cervical Vertebrae Distinguishing Characteristics
A
- Foramen in transverse process to allow blood vessels and nerves to pass
- small corpus relative to other vertebral segments
- small transverse process
13
Q
Atlas: C1
A
- looks like ring of bone, no body or spinous process
- supports weight of the skull
- joint btw atlas C1 and axis C2
- allows unlimited pivot of skull
14
Q
Axis: C2
A
- axis forms a pivot around which the atlas and skull rotate
- special landmark- ondontoid process
15
Q
Odontoid Process
A
- prevents injury to upper spinal cord by limiting pivoting
16
Q
Thoracic Vertebrae
A
- Costal (RIB) articulatory facets on transverse process and vertebral bodies allow rib artic and attach via synovial joints
17
Q
Costo-Central Articulation
A
- gliding joint created between body of vertebrae and head of rib-superior/inferior costal facets
18
Q
Costo-Transverse Articulation
A
- gliding joint created between transverse process and shaft of rib
19
Q
Lumbar Vertebrae
A
- massive corpus
- lack transverse foramen and articular facets on transverse process and vertebral bodies
- spinous process directed horizontally
- as opposed to usual dorsal and inferior direction
- holds up everything
20
Q
Sternum aka breast bone
A
- Manubrium
- Corpus
- Xiphoid Process
21
Q
Manubrium Sterni
A
- facet for collar bone and first rib
22
Q
Corpus Sterni
A
- facets for ribs 2-7
23
Q
Xiphoid Process
A
- small extention at the bottom of sternum
24
Q
how many ribs are there?
A
- 12 pairs
25
Ribs 1-10 connect with...
sternum via costal cartilage
26
Ribs 11 and 12..
are floaters....they have no attachment
27
True ribs
first 7
28
false ribs
8, 9, 10
29
floating ribs
11 and 12
30
Rib Morphology
* head and tabernacle provide articulating surface with vertebrae
31
Rib Angle
point where the rib abruptly changes direction
32
Rib Shaft
bulk of rib
33
Shoulder Girdle
consists of scapula and clavicle
34
Clavicle
articulates laterally with scapula and medially with manubrium
35
Scapula
articulates with clavicle and humerus of arm
36
Pelvic Girdle
* composed of Illium, Public bone, and sacrum
* each hip articulates with corresponding head of femur
* fused anteriorly at pubic symphysis
