Lab 1 - Superficial Thoracic Wall
- Where is the serratous anterior muscle?
- Where is the inferior angle of scapula?
- Where is the clavicle?
- What are the parts of the breasts?
- Where is the medial pectoral nerve?
- What is the action, innervation, blood supply, origin, and insertion of the serratus anterior muscle
- what nerve fibers are contained in the anterior and lateral cutaneous nerves?
- afferent, efferent, & postganglionic sympathetic
- Where do the pectoral nerves come from?
- medial and laterla cords of the brachial plexus
- What covers the pectoralis minor muscle?
- clavipectoral fascia
- Where is the medial pectoral nerve?
- What kinds of fibers are in the medial pectoral nerve?
Lab 2 - Completion of the Thoracic Wall and Overview of the Axilla
- Locate the internal intercostal muscle.
- Locate the intercostal neurovasculature. Where does it lie? What is contained in the bundle?
- Describe the intercostal nerve fiber types. Where do they come from?
- post-ganglionic symathetic, afferent or efferent fibers. come from the spinal nerve - ventral primary rami
- Show me the rib angle.
- What landmark divides the axillary artery?
- Pectoralis minor muscle
- Show me the axillary artery and where each division is located. What do the branches supply?
- 1st division: superior artery, 2nd division: thoracoacromial artery and lateral thoracic artery, 3rd division: 3 branches
- Where is the long thoracic nerve? What does it arise and what is its innervation?
- arises from C5,6,&7. innervates serratus anterior muscle "C5,6,&7 keep your wings from heaven"
- Show external, internal, innermost intercostal muscles. What direction do they run? What is their insertions and origins?
- What are the lateral & medial cords of the brachial plexus? What branches off these? How do you differentiate these cords?
- branches = lateral & medial pectoral nerves. Differentiate by their relationship to the axillary artery
- Name five things that occur at the sternal angle
- articulation of 1st rib, bifurcation of trachea, location of aortic arch, transverse plane hits in-between 4th & 5th thoracic vertebrae, separates superior & inferior mediastinum
- Name the four branches of the thorocromial artery
- pectoral, deltoid, acromial, clavicular (Think DCAP)
- Locate the supreme thoracic artery. What doe sit supply?
- supplies 1st & 2nd intercostal space
- How is the external intercostal muscle attached to the sternum?
- external intercostal membrane
- Where are the attachments for the internal & innermost intercostal muscles?
- internal = sternum to angle of the rib. innermost = costochondral junction to tubercle of rib
- Where do the anterior & posterior arteries branch from?
- anterior = internal thoracic arteries. posterior = descending aorta
- lies between the innermost & internal intercostal muscles. contains vein, artery, & nerve
Lab 3 - Pleura and Lungs
- Where will I find Pulmonary Arteries? Bronchus? What's the difference?
- Identify the pulmonary veins.
- If lung was removed, how could you tell if it was right or left?
- lobes, cardiac notch, lingual, impressions
- Where is the endothoracic fascia? What is its purpose?
- Adhesive layer to keep parietal pleura connected (glued) to ribs
- Locate the internal thoracic artery
- How do you determine the difference between the artery and vein?
- Vein-lumen sometimes has some color to it, flat
- Artery- more tubular and thicker
- How many internal thoracic veins are there?
- 2 on each side
- Are there any projections off of the internal thoracic artery?
- Yes; anterior intercostal arteries
- Where does the internal thoracic artery originate?
- Subclavian artery
- What causes the lungs to expand?
- When the thorax expands the fluid in the parietal cavity creates a surface tension that causes the lungs to expand with the parietal cavity
- What part of the lung extends out of the thoracic cavity (cage) and where does it extend over?
- Apex (Cupula) over the 1st rib & clavicle
- Identify the azogous vein impression of the lung
- Identify the costal & mediastinal portions of the parietal pleura
- Identify the Phrenic Nerve and what does it innervate? What type of nerve fibers does it contain?
- Afferent, Efferent to skeletal muscle, & Postganglionic Sympathetic Efferent
Lab 4 - Pericardium and Heart
- Identify fibrous pericardium
- How do you determine left or right dominance?
- In order to do this you identify the posterior interventricular artery and follow it to its origin. If it originated in the right coronary artery then it will be right dominance and if the left coronary artery then it's left dominance. It is usually right dominant.
- If vagus nerve increases activity what happens to the heart?
- It slows down rate of heart
- Show interventricular grooves (anterior & posterior)
- Show opening of coronary sinus. What type of blood does the coronary sinus have and what type doesn't it have?
- Has from: great, middle, and small cardiac veins
- Does not have from: anterior ?? and vena cardea minima (drains ventricles)
- How do you determine the difference between the artery and vein?
- Vein-lumen sometimes has some color to it, flat
- Artery- more tubular and thicker
- Identify parietal layer of serous pericardium. How is this related to the epicardium?
- Continues at the reflection and are in contact with one another except for the serous fluid between them
- Identify chordae tendineae
- Show me the fibrous layer of the pericardium
- Show me the visceral layer of the serous pericardium. What is this also called?
- epicardium
- Show me the openings to the inferior and superior vena cava
- What other opening is found in the right atrium besides the inferior and superior vena cava?
- opening to the coronary sinus
Lab 6 - Superior And Inferior Mediastinum
- identify the tracheal carina
- How does a blood clot in an intercostals vein get into the lungs and cause a blood clot?
- Identify the esophageal plexus. What nerves innervates this?
- Identify the vagus nerve.& nbsp; Where are its recurrent branches on each side of the body?
- identify the brachiocephalic artery.
- identify the brachiocephalic vein. What does it drain into?
Lab 8 - Survey of the Peritoneal Cavity
- identify the round ligament of the liver
- identify the falciform ligament
- identify the hepatoduodenal ligament
- What is found in the hepatoduodenal ligament?
- common bile duct, hepatic artery, portal vein, hepatic lymphatic vessels
- What is found in the suspensory ligament of the uterus?
- uterine arteries & veins
