Fetal Pig Dissection Image Sets

*All Structures must be CLEARLY identified by pins or by power point arrows placed in the images.

(Group grade given-All members get the same grade)

External Features to ID (Unit 1)Image Set #1• Nares

• Eyes & Nicitating membrane• Tongue• Pinnae• Thorax• Trunk• Umbilical cord• Teats• Urogenital opening• Scrotum (male) or Genital papilla (female)-Pg. 9• Anus• Measure length to estimate age of pig (use string and

measure from the tip of the nose to the base of the tail)****Use table on pg. 7 to estimate age.

Exploration of the NeckImage Set #3

• Sternohyoid Muscle• Larynx• Thyroid gland• Thymus gland• Trachea• Jugular vein• Carotid artery

Exploration of the Thoracic Cavity Image Set #4

• Lungs (7 lobes)-Label Left & Right Side• Diaphragm• Heart• Pericardium• Apex• Coronary artery & vein• Aortic arch• Atrium • Ventricles• Pulmonary vessels (arteries & veins)• Septum

Image Set #5 - Structures of the Digestive System• Hard palate • Soft palate• Epiglottis• Esophagus • Liver (be able to name the 4 lobes)• Stomach (be able to identify cardiac region & pyloric region)• Spleen• Gall Bladder• Mesenteric Arteries• Pancreas• Small intestine (Duodenum, Jejunum, & Ileum)• Large intestine segments (A, T, D, Sigmoid)• Cecum/Spiral colon (Fig.22 on p.35)

*Isolate the small & Large intestines*Measure the length of the digestive tract (Stomach to the anus)

Image Set #6 Further Exploration of Circulatory System• Locate & Identify the following Vessels:

– Carotid Arteries, Jugular Veins (already done in image se #3)– Subclavian artery (branches off the aortic arch)– Brachial artery (upper extremities)– Abdominal Aorta & Vena Cava (inferior)– Iliac artery – Femoral artery (lower Extremities)– Mesenteric Arteries & Veins– Portal Vein

**Know where these blood vessels can be found:-Gastric -Tibial -Hepatic -Radial-Pulmonary -Caudal

Urinary & Reproductive Systems (Image Set #7)

• Kidney (cross section of left kidney)– Renal cortex (outer layer)– Renal medulla & – Renal pelvis (inner layer)

• Adrenal gland• Ureter• Urinary Bladder • Renal artery & renal vein

• Female (uterine horns & ovary)• Male (vas deferens & testes)***Review the diagrams for the brain (pgs. 50 & 51)
