Ribs and breathing

Question 1

Rib handles

Answer 1

rib 1-5 = pump

rib 6-10 = bucket

rib 11-12 = caliper

Question 2

muscles for breathing

Answer 2

Inspiration =
diaphragm and scalenes
Accessory: SCM and Trapezius

Expiration =
In and Ex obliques
rectus and transverse abdominals
Accessory: Lat dori and QL

Both = In and Ex intercostals

Question 3

thoracic spine
mechanics

Answer 3

Most mechanically stable part of spine

To allow a secure attachments for ribs to articulate from during breathing

thorat and rib cage are a closed sealed system

this allows it to accommodate to changes in volume and to act as a bellows

provides a stable ancho for movement of upper extremity

Question 4

limiting factors of breathing
5 points

Answer 4

age
scoliosis
kyphosis
RA
obesity

Question 5

limiting factors of breathing
5 points explained

Answer 5

Age - increased muscle stiffness.
and changes in breathing patterns.
child - abdominal. Adult chest. Elderly ab.

Scoliosis - leads to excessive SB and R. affecting rib excursion and thoracic restriction

kyphosis - reduced rib excursion and thoracic expansion

RA - increased stiffness and inflammation of cartilage of sternocostal joints = reduced rib excursion

Obesity - lying on back will put more pressure on diaphragm
