Q

BOYLE’S LA

A

if A ↑ then P ↓ and if A ↓ then P ↑
When applied to the lungs this means that as the lungs expand (and their volume ↑) then the air pressure in the lungs ↓
If you increase the volume then the pressure will decrease

Q

What happens when the lungs expand?

A

as the lungs expand they create a difference in air pressure between the region internal and the region external to the lungs
then Air then rushes into the lungs in order to stabilize the difference in air pressure

Q

What are Vertebrae separated by?

A

intervertebral discs

they are fatty disk to cushion the area. Articulating a meeting between bone

22
Q

Where do Vertebrae fit together ?

A

at the articular facets

23
Q

C1

A

atlas; superior articulation with the skull, supports the skull

support the cranium

24
Q

C2

A

axis; provides pivot for the skull

Transverse foramina for vertebral artery

25
Q

T1-12

A

12 thoracic vertebrae

26
Q

What are the thoracic vertebrae Characterized by?

A

Characterized by large spinous and transverse processes

Ribs 2-9 attach to 3 different regions

27
Q

L1-5

A

Lumbar Vertebrae

28
Q

Lumbar Vertebrae

A

Larger vertebrae (L1-5) that provide attachment for abdominal and back mm, including the diaphragm

29
Q

S1-5

A

Saccral Vertebrae

30
Q

Saccral Vertebrae

A

fused and are called the sacrum

31
Q

Coccyx

A

fused vertebrae

32
Q

what is the first rib?

A

The clavicle

33
Q

What are the names of the first two vertebrae?

A

Atlas and Axis

atlas is the first one and axis is the second one

34
Q

What is the posterior portion of the vertebrae called?

A

Spinous process

this is the sticky and bony part

35
Q

What is the anterior portion of the vertebrae called?

A

corpus

this is the thick part

36
Q

What is the lateral portion of the vertebrae called?

A

Transverse processes

37
Q

What is the name of the hole in the vertebra that the spinal cord passes through ?

A

Vertebral Foraman

38
Q

The name of the holes between the vertebrae that nerves exist?

A

Intervertebral foramina

39
Q

Intervertebral discs

A

They separate the vertabrae

40
Q

Articular facets

A

is where the vertebrae meet. like they are name something articualt facet ex superior articular facet but it indicades thats where the vertebrae meet

41
Q

Transverse foraman

A

holes where the arteries travel. only the atlas and axis have it

42
Q

facet

A

Where bone meet

43
Q

Odontoid process

A

it fits like a lock/key in the C1

44
Q

Costal

A

Means related to the ribs so any where it says costal facet is where ribs attach

45
Q

Articular facet

A

means when the superior vertebrae meets with other vertebrae

46
Q

Pelvic girdle

A

provides structure for attachment of the lower appendages to the vertebral column

47
Q

Components of the pelvic girdle

A

ilium, sacrum, pubic bone and ischium
ilium supports abdominal musculature
Sacrum articulates with L5

48
Q

Bones that make up the pelvic girdle?

A

Ilium
Ischium
Pubis

49
Q

Why the cervical vertabrae important?

A

The are important because first 7 and they are the ones below the cranium

50
Q

what way and to what do the ribs attach?

A

The ribs attach anteriorly to the sternum

51
Q

Pectoral girdle

A

provides structure for attachment of the upper appendages to the vertebral column

52
Q

Components of the pectoral girdle

A

scapula and clavicle
