name cutaneous muscles of the trunk
cutaneous trunci, cutaneous omobranchialis, preputial muscle, supramammary
epaxial muscle definition
lie dorsal to the transverse process of vertebrae, parallel muscles, extend vertebral column
innervation of epaxial muscles
dorsal branches of spinal nerves
transversospinalis system
epaxial m, between the transverse process and spine of the vertebrae, most medial
longissimus system
epaxial m, longest, intermediate group
iliocostalis system
epaxial muscle, most lateral
hypaxial m definition
lie ventral to the process of the vertebrae
innervation of hypaxial m
ventral branches of spinal nerves
muscles of inspiration
diaphragm, scalenus, serratus dorsalis cranialis
muscles of expiration
serratus dorsalis caudalis, external abdominal oblique
inspiration facts
active process, enlarge thorax cavity to get air in, rotate ribs craniolaterally
expiration facts
largely passive, diminish thoracic cavity expelling air, rotate ribs caudomedially
fiber direction of external intercostal m
caudoventrally
fiber direction of intercostal m
caudodorsally
cranial border thoracic cavity
thoracic inlet
dorsal border thoracic cavity
thoracic vertebral bodies
ventral border thoracic cavity
sternum
caudal border of thoracic cavity
diaphragm
lateral border of thoracic cavity
ribs, costal cartilage, intercostal muscles
dorsal thoracic inlet border
body of first thoracic vertebrae
lateral thoracic inlet border
first pair of ribs and their costal cartilages
ventral thoracic inlet border
first sternebra
thoracic cavity contents
trachea, lungs, heart, thymus, esophagus, lymph nodes, vessels, nerves, plural cavities, pericardial cavity
thoracic inlet contents
trachea esophagus vagosympathetic nerve trunk recurrent laryngeal nerves, phrenic nerves, ventral branches of T1/2 spinal nerves, blood vessels and pleural cupulae
lumbocostal arch
sympathetic trunk and major splanchnic nerve
aortic hiatus
aorta, azygos vein, and thoracic duct
esophageal hiatus
esophagus, dorsal, ventral vagal trunks
caval foramen
caudal vena cav
endothoracic fascia
connective tissue lining the thoracic cavity and attaching to pleura to the thoracic wall and diaphragm
mediastinum definition
space between left and right pleural sacs
mediastinum contents
thymus, lymph nodes, heart, aorta, trachea. esophagus, nerves and vessels
visceral pleura
pulmonary pleura, lines the lungs
parietal pleura
costal pleura, mediastinal pleura, diaphragmatic pleura
connecting plurea
ligaments and folds
open pneumothorax
parietal pleura ruptures
closed pneumothorax
visceral pleura is ruptured
connecting pleura
doubled layered folds of pleura
plica venae cava
a fold of the right mediastinal pleura that envelops the caudal vena cava and right phrenic nerve
line of pleural reflection
junction between costal and diaphragmatic pleura
costodiaphragmatic recess
potential space where the diaphragmatic and costal parietal pleura are in contact with each other
number of lobe in left lung
2
names of lobes in left lung
cranial caudal lobes
parts of cranial lobe left lung
cranial and caudal parts
number of lung lobes in right lung
4
names of right lung lobes
cranial, caudal, middle, accessory lobes
cardiac notch
where heart can be accessed with a needle without hitting the lungs, 4th5th intercostal space
