Anatomy Flashcards
pericardial cavity fills with blood
haemopericardium
pressure around heart from blood in pericardial cavity can cause
cardiac tamponade
Pericardiocentesis
Drainage of fluid from the pericardial cavity
Need inserted via infrasternal angle and directed superoposteriorly, aspirating continuously
Transverse pericardial sinus
Space within pericardial activity
Lies posterior to ascending aorta and pulmonary trunk
Used to isolate great vessels to commence cardiac bypass
Surgeons finger tip emerges from sinus anterior to SVC
Palpation for apex beat
5th intercostal space midclavicular line
atrial septal defect
hole in interatrial septim
ventricular septum defect
hole in interventricular septum
tricuspid valve
between right atrium and right ventricle
pulmonary valve
between right ventricle and pulmonary trunk
mitral (bicuspid) valve
between left atrium and left ventricle
aortic valve
between left ventricle and aorta
1st heart sound ‘lub’
made
postcentral gyrus of parietal lobe
AP’s arriving here bring body wall sensations to consciousness
Precentral gyrus of frontal lobe
AP’s originating here bring about contractions of body wall skeletal muscle
Sharp Chest Pain Sources
Herpes Zoster (Shingles) Muscle, joint and bone Parietal Pleura
Dull visceral chest pain sources
Trachea Aorta Abdominal viscera Heart Oesophagus
Thoracic inlet
Bound by ribs 1, T1 vertebrae and jugular notch
Bronchopulmonary lymph nodes
surround main bronchus at lung root
Tracheobronchial lymph nodes
Around bifurcation of trachea
Right recurrent laryngeal nerve
hooks under subclavian artery
Left recurrent laryngeal nerve
hooks under arch of aorta
Referred pain from diaphragm
Presents in shoulder tip as supraclavicular nerves supply dermatomes enter spinal cord at same level as phrenic nerve
