Thorax Anatomy Flashcards
(18 cards)
What are the main elements of the Thorax?
Heart
Lungs
Mediastinum
Most of Oesophagus
Distal part of Trachea
Thoracic Skeleton
12 pairs of ribs
12 thoracic vertebrae & intervertebral discs
Sternum
Cartilage
How many are there of the below:
True ribs
False ribs ( how many are Floating ribs)
7 pairs
5 pairs (2 pairs)
What is found between each rib?
Intercostal muscles
What is the most helpful Thoracic Vertebrae when setting up?
Spinous process
What travel through the vertebral foraman?
Spinal Cord
Location & Role of Intervertebral Disc
Between Vertebrae
Shock absorbers and allows movement between vertebrae, while also maintaining spinal stability.
Where do you find all three of the below:
Manubrium
Body
Xiphoid Process
Sternum
What is the Pectoral Girdle?
Set of bones connecting upper limb to axial skeleton
Main difference between L&R Lung
LL is smaller - Cardiac Notch
LL has 2 lobes (upper & lower)
RL has 3 lobes (upper, middle, and lower lobes)
Role of Lung
Take deoxygenated blood via pulmonary artery from the heart – Deliver oxygenated to the heart via two pulmonary veins.
What play a crucial role in the spread of carcinoma cells?
Lymphatic Plexus
How many ml does the thorax volume change when the diaphragm moves?
500ml each time
Which out of the three are factors of Breathing Mechanisms?
The pleural cavity must form a negative pressure between the parietal surface of the lungs and the thoracic wall.
The contraction and relaxation of the diaphragm
The contraction and relaxation of skeletal muscles that cause movements of the ribs.
All 3
Thyroid Function
Produce and release thyroid hormones, which regulate the body’s metabolism, growth, and development.
Thymus Function
to produce and mature white blood cells called T lymphocytes (T cells), which are crucial for the body’s immune system.
What double walled Fibroserous sac encloses the heart?
Pericardium
What are the three different pace makers and their function?
Natural - Sinoatrial node (located in right atrium)
Diagnostic - To evaluate and improve patient care by providing data on pacemaker function, lead performance, and arrhythmia occurrences.
Therapeutic - Medical device implanted in the chest to regulate the heart’s rhythm.
