Thorax and Abdomen Flashcards
Runs from the base of the neck to the diaphragm
Thorax
What 3 things does the thorax contain?
Thoracic vertebrae, Ribcage, Sternum
Function of the Thorax?
Protect Respiratory and Circulatory organs. Assist the lungs in inspiration and expiration during the breathing process
Ribs 1-7
True Ribs
Ribs 8-10
False Ribs
Ribs 11-12
Floating Ribs
Between the ribs
Intercostals
Separates thorax from abdomen
Diaphragm
Contracts to allow for thoracic cavity to increase in size during inspiration
Diaphragm
Contracts and relaxes to allow for ribs to move during inspiration and expiration
Intercostals
How does the diaphragm contract?
Inferiorly
Causes air to be pulled into the lungs?
Diaphragm
Lies between diaphragm and pelvis
Abdomen
What does the diaphragm contain?
Vertebral column, Abdominal muscles, and Organs
Functions of the Abdomen?
Trunk movement and to protect organs
Functions of the Internal Oblique?
Helps diaphragm expand the thoracic cavity, Rotation, and Lateral Flexion
Functions of the External Oblique?
Trunk Flexion, Limited Rotation, and Lateral Flexion
Functions of the Rectus Abdominis?
Trunk Flexion and Assists in breathing
“Corset muscle”
Transverse Abdominis
Functions of the Transverse Abdominis
Thoracic cavity expansion, Labor delivery, and Core stability/bracing
MOI for Rib Contusions
Direct blow to ribs, damaging the rib or intercostal muscle
S/S for Rib Contusions
Sharp pain with breathing, point tenderness, pain when rib cage is compressed
TX for Rib Contusions
PRICE and NSAIDs, Possible bed rest
MOI for Rib Fractures
Direct impact or by compression of the rib cage
Most common ribs fractured?
5-9
S/S for Rib Fractures
Severe pain with breathing, point tenderness with palpation
T/X for Rib Fractures
Support and rest, usually 3-4 weeks
Are lung injuries common or rare?
Rare
MOI for Pneumothorax injury
Pleural cavity surrounding the lung become filled with air that has entered into an opening in the chest. As the pleural cavity fills with air, the lung on the same side, collapses
MOI for Tension Pneumothorax injury
Pleural cavity on one side fills with air and displaces the lung and heart toward the opposite side. Compress the opposite lung
Blood within the pleural cavity
Hemothorax
Direct blow to the lung or compression of the rib cage
Traumatic Asphyxia (life threatening condition)
Stops breathing rhythm and requires immediate CPR and emergency care
Traumatic Asphyxia
What can Hemothorax be caused from?
Tearing or function of the lung or pleural tissue
S/S for Lung Injuries
Difficulty breathing/ shortness of breath, chest pain on side of injury, coughing up blood, cyanosis, potential shock, total collapse of the lung
TX for lung injuries
Immediate attention
Most common cause of exercise-induced sudden death is a ______________
congenital cardiovascular abnormality
Thickening of the cardiac muscle
Hypertrophic Cardiomyopathy
1 of the 2 coronary vessels originates in a different sight than normal
Anomalous origin of the Cardiac Artery
Abnormality of the connective tissue resulting in weakening of the aorta and cardiac valves which can lead to the rupture of the valves or the aorta itself
Marfan’s Syndrome
Hardening of the arteries due to high cholesterol in young athletes
Coronary Artery Disease (CAD) - becoming more common
What are some Noncardiac causes of Sudden Death Syndrome?
Drug use in athletes, Vascular bleeding in the brain caused by a cerebral aneurysm or head trauma, or obstructive respiratory diseases (Ex: asthma)
S/S of Sudden Death Syndrome
Chest pain or discomfort during exertion, hear palpitations or flutters, syncope, nausea, profuse sweating, heart murmurs, shortness of breath, fever
TX for Sudden Death Syndrome
Use symptoms as a medical emergency
Prevention of Sudden Death Syndrome
Counseling, screening and early identification of preventable causes of Sudden Death Syndrome
Protrusion of the abdominal viscera through a portion of the abdominal wall.
Hernia
What are the two types of Hernias?
Inguinal and Femoral
MOI for a Hernia
Intra-abdominal tension is produced and the muscles fail to react causing abdominal contents to fall through the opening.
S/S for a Hernia
Previous injury to groin, superficial protrusion in groin/thigh that is increased with coughing, weakness and pulling sensation in groin/ thigh
TX for a Hernia
Restricted activity, possible surgery
