Anatomy Of Coughing Flashcards
What are the 2 steps in coughing?
Stimulation of sensory receptors in the mucosa Oropharynx Larngopharnynx Larynx Respiratory tree Rapid response in the CNS
What nerves are stimulated in sneezing?
CNV and CNIX
Trigeminal and glossopharyngeal
What nerves are stimulated in coughing?
CNIX and CNX
Glossopharyngeal and Vagus
What are the Carotid Sheaths?
Protective tubes of the cervical deep fascia
Where do the Carotid Sheaths attach and blend?
Attach superiorly to bones of base of skull
Blends inferiority with fascia of mediastinum
What is contained within the Carotid Sheaths?
Vagus Nerve (CNIX)
Internal Carotid Artery
Common Carotid Artery
Internal Jugular Vein
What is the Pulmonary Plexus?
Route through which the visceral pleura and Respiratory tree visceral afferents connect with the CNS
What intercostal muscles is used for inspiration?
External intercostal
What are the accessory muscles of inspiration?
Pec major
Pec minor
Sternoeidomastoid
Scalenus anterior, medius and posterior
Pec major attachments and breathing?
Between sternum and humorous. Addicts medically and rotates humerus.
If upper limb fixed muscle pulls ribs up and out.
Pec minor breathing?
Pulls ribs 3-5 towards the coracoid process of scapula.
Sternoeidomastoid attachments?
Between sternum/clavicle and mastoid process of the temporal bone.
Attachments of scalenus anterior, medius and posterior?
Attach between cervical vertebrae and ribs 1 and 2.
What does the addiction of the vocal cords do?
Close the rima glottidis
What nerve supplies the intrinsic muscles of the larynx?
The vagus nerve
What do the intrinsic muscles of the larynx do?
Adduct the vocal cord
Vagus nerve connections?
Connect with the CNS at the medulla of the brain stem.
Where does the vagus nerve pass through?
Jugular foramen
The path of the vagus nerve
Descend through Carotid Sheath
In the chest descend posterior to lung root supplying parasympathetic axons to chest organs.
Pass through diaphragm on the orsophagus.
At the stomach divides into parasympathetic branches to supply the foregut and midgut.
What does contraction of the anterolateral abdominal wall muscles do?
Build up intra-abdominal pressures, pushing diaphragm superiorly building up pressure in the chest and respiratory tree inferior to the addicted vocal cords.
What are the antrrolateral abdominal wall muscles?
Rectus abdominus
External oblique
Internal oblique
Transversus abdominus
What is the aponeurosis?
Flat sheet of tendon like material that anchors a muscle or connects it with the part that the muscle moves.
In what direction does the external oblique run?
Hands in pocket
What is the linea Alba?
Where the aponeuroses blend
Line in 6 pack
Superior attachment of the external oblique.
Superficial aspects of the lower ribs.
Inferior attachment of the external oblique.
Illiac crest and public tubercle
What is the linea semilunaris?
Where the muscle fibres end and the aponeurosis begins.
What way does the internal oblique run?
Opposite form external oblique.
Superior attachment of internal oblique
Inferior border of the lower ribs
Inferior attachment of the internal oblique
Illiac crests and the thoracolumbar fascia of the lower back
What diresction does the Transverese Abdominus run?
Straight across allowing us to twist and contract
Superior attachment of Transverse Abdominus
Deep aspects of lower ribs
Inferior attachment of Transverse Abdominus
Illiac corset and thoracolumbar fascia of lower back.
What is the rectus sheath composed from?
The aponeuroses of the other 3 muscles.
What do the tendinous intersections of the rectus Abdominus do?
Divide the 2 long muscles into 3 or 4 smaller quadrants muscles which improved mechanical efficiency.
Where do the 7th-11th intercostal nerves terminate and what do they become?
Leave intercostal spaces in plane between internal oblique and Transverse Abdominus
Become thoracoabdominal nerves
Subcostal nerve ramus?
T12 anterior
Ramus of iliohypogastric nerve
Half of L1 anterior ramus
Ramus of ilionguinal nerve
Half of L1 anterior Ramus
What is ‘Guarding’?
Protects the abdominal viscera. Can’t indicate appendicitis.
What nerves causes the soft palate to tense and elevate?
CNV and CNX
What does the elevation of the soft palate do?
Closes of the nasopharynx and directs the air through the oral cavity.
