11 Review of last lab’s vessels

12 Objectives for Lab 5 Identify the veins listed below in a human model or photograph of a human. Identify the veins listed below on a dissected cat or photograph of a cat. Describe the layers/tunics and histological characteristics of veins. Trace the path of a drop of blood through the arteries AND veins, including the heart and pulmonary circulation.

13 Comparison of Walls of Arteries and Veins Smooth muscle of the tunica media in both arteries and veins is innervated by the sympathetic nervous system. Figure from: Hole’s Human A&P, 12 th edition, 2010

14 Major Vessels of the Venous System Figure from: Hole’s Human A&P, 12 th edition, 2010

15 Major Veins of the Brain, Head, and Neck * * * * * External jugular v. drains blood from face, scalp, and superficial neck regions Figure from: Hole’s Human A&P, 12 th edition, 2010

16 Major Veins of the Brain, Head, and Neck Figure from: Martini, Anatomy & Physiology, Prentice Hall, 2001

17 Location of Internal and External Jugular V. External Jugular v. Internal Jugular v. SCM Figure from: Anatomy & Physiology Revealed, 2010

18 Major Veins - Upper Limb and Shoulder * * * * * * * Median cubital vein is often used to draw blood (venipuncture) * * * (deep) (superficial) Figure from: Hole’s Human A&P, 12 th edition, 2010 * *

19 Major Veins - Upper Limb and Shoulder Figure from: Martini, Anatomy & Physiology, Prentice Hall, 2001 Note the deep veins (radial, ulnar, brachial) and the superficial veins (cephalic, basilic, median cubital) of the upper limb

20 Veins That Drain the Abdominal Viscera * * * Figure from: Martini, Anatomy & Physiology, Prentice Hall, 2001 * * * * *

21 Main Veins of the Lower Limb and Pelvis * * * * * * * Figure from: Hole’s Human A&P, 12 th edition, 2010 *

22 Cat Blood Vessel Dissection Schedule Blood vessel labs –Dissection 1(1 st lab - arteries above diaphragm and upper limb) Preparing the cat (see page 706 in Marieb) Cardiovascular (pp in Marieb) –Dissection 2 (last lab - arteries below diaphragm and lower limbs) Arteries below diaphragm (see Marieb) –Dissection 3 (today - all veins; review arteries) Veins (see Marieb)

23 Reminders for Cat Dissection You must wear gloves and goggles for this lab! ABSOLUTELY NO FOOD OR DRINK Be EXTREMELY careful when using the scalpels –Keep your index finger on the top of the blade –Be careful not to inadvertently cut structures Use a blunt probe, or your gloved fingers to dissect away tissue. Use the scalpel ONLY for initial cutting. Proceed S-L-O-W-L-Y. Discard scraps/liquid into the appropriate container Gloves, paper towels, plastic bags -> regular trash

24 Continuing with Cat Dissection… Work in groups you formed for dissection of arteries Get some paper towels and keep them at your lab table Get your instruments and dissecting tray (large trays in the front of the lab) ready Get a cat and cut open the sealed bag but don’t discard the fluid; you’ll be using this cat all semester and replacing the fluid each time. Let the cat out of the bag - again! You should be able to locate all the veins listed in your Lab Guide

35 Things you should do in lab today Examine the vein slide under the microscope –Name/identify the layers of the vein –Describe how each layer (tunic) is constructed –Refer to Marieb’s Lab Manual Figure 32.2 right side Perform cat dissection of veins listed for Lab 5. See Marieb’s Lab manual pp for instructions. Review human veins listed for Lab 5 Complete Lab 5 Assignment on a separate sheet of paper, put your name on it, and hand it in today. –Use figures 32.8 – as a guide

36 Next Lab… Blood Pressure –Read ahead: Exercise 33 in Marieb’s Lab Manual –Review the handout (available online) ECG (EKG) –Read ahead: Exercise 31 in Marieb’s Lab Manual –Review the handout (available online – same one as for BP) Wear comfortable clothes/shoes since you’ll be exercising!
