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.

Major Veins of the Brain, Head, and Neck
External jugular v. drains blood from face,
scalp, and superficial neck regions

Major Veins - Upper Limb and Shoulder




Median cubital vein is often used to draw blood

(superficial)

Major Veins - Upper Limb and Shoulder
Note the deep veins (radial, ulnar, brachial) and
the superficial veins (cephalic, basilic, median
cubital) of the upper limb

Cat Blood Vessel Dissection Schedule
  • Blood vessel labs
  • Dissection 1(1st lab - arteries above diaphragm
    and upper limb)
  • Preparing the cat (see page 706 in Marieb)
  • Cardiovascular (pp. 733-741 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 -gt 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 dont
    discard the fluid youll 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

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 Mariebs Lab Manual Figure 32.2 right
    side
  • Perform cat dissection of veins listed for Lab 5.
    See Mariebs Lab manual pp. 737-741 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 32.15 as a guide

36
Next Lab
