what are the articular surfaces located on either side of the jugular notch that attach to the clavicle
SC Joints
this part of the rib divides into medial(articular) and lateral (non articular) portions
tubercle
what is centered over true midline of the anterior thorax and is directed anteriorly and inferiorly
sternum
the inferior border of the shaft of the rib is what
grooved for attatchment of muscles of the placement of the nerves and vessels
what is approximately one inch long and lies anterior to the transverse process of the numerically corresponding vertebrae
Neck of the rib
at what level is the xiphoid process located anatomically
level of T10 or brachial angle
what is located at the distal end of the sternum and is the smallest portion of the sternum
xiphoid process
at what level is the sternal angle located at anatomically
the level of the fourth and fifth thoracic vertabrae
where does the gladiolus and the manubrum articulate at
sternal angle
what is another name for the body of the sternum
gladiolus or corporus
what is located on the superior border of the manubrum at the level of the interspace of the second and third thoracic vertebrae
jugular notch
what is the most superior and widest part of the sternum
manubrium sterni
what supports the clavicle and provides attatchment to the seven pairs of ribs
sternum
what forms the anteior portion of the rib and terminates at the oval facet
shaft
what is the internal surface of the shaft covered by
a pleural lining
the superior border of the shaft is what
rounded and smooth
what is the thin, flat, elongated portion of the rib that extends beyond the tubercle
shaft
located at the junction of the neck and the shaft of the rib
tubercle
which rib/s join together via a common costal cartilage which articulate indirectly with the sternum by means of the costal cartilage
eighth through tenth ribs (false ribs)
which rib/s only has one facet and articulate with their corresponding vertebral body
first, tenth, eleventh, & twelfth rib
how is the thoracic cage formed inferiorly
by the diaphragm
what is located between the head and the articulating part of the tubercle of the rib
neck
which is the larger demi facet that articulates with the body of the numerically corresponding vertebrae
the lower demi facet
what seperates the the two demi facets on the head of the rib
interarticular crest
the head of the rib is divided into two parts called what
demi facets
what is the posterior or vertebral end of the rib that articulates with the body of the thoracic vertebrae
head
the internal surface of the ribs are considered to be what
concave
the external surface of the ribs are considered to be what
convex
the inferior border of each rib is considered to be what
thin, sharp, and grooved
the superior border of each rib is considered to be what
smooth and rounded
what attatches to the inferior border of the ribs
vessels and nerves
which rib/s has costal cartilage present on the anterior aspect of each rib, but do not articulate with any bony or cartilaginous structure
eleventh and twelfth ribs (floating ribs)
what are the eleventh and twelfth ribs called
floating ribs
what are the eighth through twelfth ribs called
false ribs
which rib/s articulate with the gladiolus and xiphoid at the xiphisternal joint
seventh rib
which rib/s articulate directly to the gladiolus solely
third through sixth ribs
which rib/s articulates with the manubrum and the gladiolus at the sternal angle
second rib
which rib/s articulates directly with the manubrum just below the sterno-clavicular joint
first rib
what are the first through seventh pair of ribs called
true ribs
what seperates the ribs
intercostal spaces
what is a long, narrow, curved bone with an anteriorly attatched piece of hyaline cartilage
ribs
how are the ribs situated
they are situated in an oblique plane slanting anteriorly and inferiorly
how are the ribs numbered
consecutively from superiorly to inferiorly
how many ribs are there
12
what are the ribs designed to provide
support for the chest wall
ribs are classified as what type of bones
flat bones
what are the four factors affecting lung capacity
size
posture
fluid
disease
how does the female thorax differ from the male thorax
less capacity
sternum is shorter
cranial margin of the sternum is at the level of T3 versus T2 for males
upper ribs are more moveable & allow for greater enlargement of the upper portion of the thorax
what are the purposes of the thorax
protects the viscera in the thoracic and upper abdominal cavities
supports the shoulder girdel & upper limbs
provides attatchment points for muscles
plays a role in breathing
what is included in the lymphatic system
thoracic duct
associated lymph vessels and nodes
digestive esophagus
what does the circulatory system contain
heart
vena cava
what does the respiratory system contain
lungs
trachea
bronchi
what are the main contents of the thorax
respitory system
circulatory system
lymphatic system
what is the shape of the thorax in a transverse sectional view
kidney shaped
what forms the floor of the thorax and where is it located anatomically
diaphragm and inferior portion
where is the apex of the thorax anatomically
superior aspect
what is the shape of the thorax
conical
how is the thoracic cage formed superiorly
by the first thoracic vertabrae, cranial margin of the sternum, and first pair of ribs
how is the thoracic cage formed laterally
by the ribs, the muscles and membranes which occupy the 11 intercostal spaces between the ribs
how is the thoracic cage formed anteriorly
by the sternum and the coastal cartilages
how is the thoracic cage formed posteriorly
by the 12 thoracic vertebrae and the dorsal parts of the 12 ribs
