Intervertebral joint
(type, articulation, ligament)
T: syphysis
A: adjacent vertebral bodies bound via IV disc
L: anterior/posterior ligament
Costovertebral Joint
head of the rib (T,A, L)
T: synovial plane
A: head of rib 4 with superior demi-/costal facet of T4 and inferior demi-/costal facet of T3
L: radiate and intra-articular ligament
Costotransverse Joint
(TAL)
T: synovial plane joint
A: tubercle of rib with transverse process of vertebra of same number
L: costotransverse lateral and superior.
Costochondral joint
(TAL)
T: primary (hyaline cartilaginous)
A: lateral end of costal cartilage with sternal end of rib
L: Cartilage and bone bound by periosteum
Interchondral Joint
(TAL)
T: synovial plane joint
A: between costal cartilage of 6/7, 7/8, 8/9 ribs
L: interchondral ligament
Sternocostal Joint
(TAL)
T: 1st is a primary cartilaginous joint. ribs 2-7 are synovial plane joint
A: articulates with manubrium costal cartilages. 2-7th pairs of costal cartilage with sternum
L: ant/post radiate sternocostal ligament
Sternoclavicular Joint
(TAL)
T: saddle type synovial
A: sternal end of clavicle, manubriumm and 1st costal cartilage
L: ant/post sternoclavicular
Manubriosternal Joint
(TAL)
T: secondary cartilaginous joint
A: articulates between manubrium and sternal body
L: none
Xiphisternal Joint
(TAL)
T: primary cartilaginous joint
A: articulate between the sternal body and xiphoid process.
L: none
Label the following diagram
Serratus Posterior Superior
(attachment, innervation, action)
Attach: nuchal ligament, spine porcess, superior rib border
Inner: 2-5th intercostal nerve
Action: proprioception, and elevates rib
Serratus Posterior Inferior
(attachment, innervation, action)
attach: spine process and inferior border of 8-11 ribs
Inner: anterior rami T9-T12 spinal nerves
Action: proprioception, depress ribs
Levator Costarum
(attachment, innervation, action)
Attach: Transverse process T7-T11
Inner: subjacent ribs between tubercle and angle
Action: elevate ribs
External Intercostal Muscle
(attachment, innervation, action)
attach: inferior rib border and superior border
Inner: intercostal nerve
Action: elevate during forced inspiration
Internal Intercostal Muscle
(attachment, innervation, action)
Attach: inferior border and superior border of ribs
Inner: intercostal nerve
Action: interosseous portion depresses ribs
interchondral portion elevate ribs
only during forced respiration
Innermost Interchondral Muscle
(attachment, innervation, action)
Attach: inferior and superior border of ribs
Inner: intercostal nerve
Action: interosseous portion depresses ribs
interchondral portion elevates ribs
Subcostal Muscle
(attachment, innervation, action)
Attach: internal surface of lower rib and superior border 2-3 ribs below
Inner: intercostal nerve
Action: potentially elevate ribs during forced inspiration
Transversus Thoracis Muscle
(attachment, innervation, action)
Attach: posterior surface of lower sternum and internal surface of costal cartilage 2-6
Inner: intercostal nerve
Action: weak depression of ribs, higher probability of proprioception
What are the atypical ribs and how can they be different?
ribs 1,2,11, 12.
Differ in size, shape, and articulations
Vertebrocostal is another way to refer to______?
vertebrocostal refers to the true ribs, 1-7
Vertebrochondral refers to what # of ribs?
8-10, and these are also called false ribs
These ribs “fuse” cartilage with the 7th rib joint
Ribs 11, 12 are considered what?
floating ribs
What innervates the diaphragm?
Phrenic nerve C3-C5
which consists of both cervical and brachial plexus contributions.
