Pulmonary Apparatus and Chest Wall
- chest wall
- Rib cage
- ribs and costal cartilage
- sternum
- pectoral girdle
- vertebral column (thoracic)
- Muscles of Rib Cage Wall
- muscles of anterolateral neck
- Sterno Cliedo Mastoid
- origin- sternum and clavicle
- insertion- mastoid process of skull
- function- unilateral contraction,
brings sternum and clavicle
closer to mastoid process
- innervation- Cranial nerve 11 accessory nerve
- innervation- Cranial nerve 11 accessory nerve
- Class 1 Lever
- bilateral contraction, flexes neck, raises sternum
- bilateral contraction, flexes neck, raises sternum
- origin- sternum and clavicle
- Anterior Scalene
- origin- C3-C6 vertebrae (cervical)
- insertion- 1st rib

- pectoralis major
- origin- medial half of
clavicle, ribs 2-6,
sternum,
aponeuroses of
external oblique
- insertion- humerus
- function- adduct and
rotate arm medially,
raises ribs 2-6, and
raises sternum
- origin- medial half of
clavicle, ribs 2-6,
sternum,
aponeuroses of
external oblique
- pectoralis minor
- origin- scapula
- insertion- rib 2-5

nerve (8th cervical and 1st
thoracic spinal nerves
- origin- scapula
- serratus anterior
- origins- ribs 1-8 or 9
- insertion- scapula
- innervation- long
thoracic nerve (5th-7th
Cervical spinal nerves
- functions- protracts and
rotates scapular, rely on
muscle to hold close to
thoracic wall
- origins- ribs 1-8 or 9
- pectoralis major
- Deep
- diaphragm
- Muscles of diaphragm
- central tendon
- origins at xiphoid process of
sternum, cartilage of ribs 7-12
and upper lumbar vertebrae
- flattens when it contracts, increases volume of
thoracic cavity controlled by phrenic nerve
(3rd-5th Cervical spinal nerves
- origins at xiphoid process of
sternum, cartilage of ribs 7-12
and upper lumbar vertebrae
- central tendon
- Muscles of diaphragm
- external and
internal intercostals
- occupy spaces between ribs (11)
- downward and medially
- innervated by intercostal muscles
- function- muscles of inhalation
and raise and lateralize ribs
- function- muscles of inhalation
and raise and lateralize ribs
- deep to external
- interosseous- stiffen
spaces between ribs and
lower ribs
- raise ribs
- raise ribs
- interosseous- stiffen
spaces between ribs and
lower ribs
- occupy spaces between ribs (11)
- transverse thoracic
- origin- sternum,
xiphoid process,
cartilage of ribs 5-7
- insertion- ribs 2-6
- innervation- intercostal muscles
- origin- sternum,
xiphoid process,
cartilage of ribs 5-7
- diaphragm
- Rib cage
- diaphragm
- shaped like inverted bowl (open parachute)
- separates thorax from abdomen, flexible
- separates thorax from abdomen, flexible
- shaped like inverted bowl (open parachute)
- Abdominal Wall
- abdominal muscles
- connective tissues
- vertebral column (lumbar, sacral, coccygeal)
- pelvic girdle
- abdominal Contents:
- stomach
- intestines
- internal organs
- compressible- creates pressure in abdominal cavity- intra-abdominal pressure
- make it possible to shunt pressure between rib cage and abdomen
- make it possible to shunt pressure between rib cage and abdomen
- stomach
- abdominal muscles
