anatomy Flashcards
at level of C6 what anatomically changes in terms of larynx and pharynx
larynx becomes trachea
pharynx becomes oesophagus
which fissure is in both lungs
oblique
name the fissure in the left lung
oblique
how does a rib articulate with the sternum
via its costal cartilage
where is the phrenic nerve found
neck on the anterior surface of scalenus anterior
descending over the lateral aspect of the fibrous pericardium anterior to the lung root
what does the phrenic nerve supply to the diaphragm
somatic motor
phrenic nerve supplies somatic sensory and sympathetic to what
fibrous pericardium
mediastinal parietal pleura
diaphragmatic parietal pleura
diaphragmatic parietal peritoneum
what types of muscles are in the larynx
all skeletal muscles-voluntary
where do the muscles of the larynx attach
between the cartilages, move the cartilages move the vocal cords
what are the muscles of the larynx supplied by nervouslu
somatic motor branches of the vagus nerve
what type of nerve is the vagus nerve
mixed cranial nerve
where does vagus nerve pass through the skull
jugular foramen
how does vagus nerve pass from neck to thorax
within the carotid sheath
does vagus nerve descend anterior or posterior to the lung root
posterior
how does the vagus nerve connect with the CNS
at the medulla oblongata of the brainstem
what is the rima glottidis
the opening between the true vocal cords and the arytenoid cartilages
how does the vagus nerve reach the abdomen
passes through the diaphragm on the oesophagus
where does the external oblique muscle attach
superiorly to the superficial aspects of the lower ribs
inferiorly to the anterior part of the iliac crest and the pubic tubercle
where does the internal oblique attach
superiorly- the inferior border of the lower limbs
inferiorly-the iliac crest and the thoracolumbar fascia of the lower back
where does the transversus abdominus attach
superiorly- deep aspects of the lower ribs
inferiorly-the iliac crest and the thoracolumbar fascia of the lower back
