I. External Anatomy

A. Task #1
  • lateral view


  • ventral view

4. glossary:
  • dorsal - the upper surface or back
  • ventral - on the upper side (opp. of dorsal)
  • anterior - situwated closer to the head
  • posterior - situwater farther from the head (closer to the tail)
  • pectoral - the shoulder region
  • pelvic - the hip region
  • head - cranial
  • trunk - thoracic and abdominal
  • thorax - anterior side of the trunk
  • abdomen - posterior side of the trunk
  • medial - toward the mid line of the body/pig
  • caudal - toward the tail (inferior)
  • cranial - toward the head (superior)
  • umbilical cord - procurment of food and oxygen for the fetus from the mother
  • mammary papillae - the nipples that the young feed of of when the pig is mature
  • proximal - discribes the part of a structure nearest a point of reference
  • distal - Farthest from the point of attachment
  • lateral - toward the outside of the body.pig
  • left - the pigs left
  • right - the pigs right

B. Task #2
1. Include a photo of the pig's head and label the following structures:


2. Include a photo showing the structures that distinguish a female pig. Label the following:

3. Include a photo that distinguishes a male pig. Include the following labels:

4. Include a photo of a dissected umbilical cord. Label:

5. Include a photo showing joints and structures of the pig's legs. Label the following:

6. glossary:
  • pinnae: the external ears
  • eye: made up of an upper and lower eyelid and a greatly reduced nictitating membrane
  • nictitating membrane: Plica semilunarisy
  • eyelids: hides the nictitating membrane and protects the eye itself
  • urogenital opening: male- consists of the penis
  • urogenital papillae: female- urinary and genital passages
  • anus: the Teminal opening of the digestive track
  • scrotal sacs: scrotum containing the testes
  • artery: branches of the Aorta
  • vein: alowes blood to travle throw the pigs body
  • ankle: similar to the wrist and located below the knee
  • knee: similar to the elbow but located ventral/posterior
  • wrist: located on the ventral/anterior aspect just below the elbow
  • elbow: also located ventral/anterior aspect right below the shoulder on the same legs as the wrist
  • toe: hooves
7. Research and discuss the function of the umbilical veins and arteries(distinguish between the two).
umbilical vains: the vains carry nutrients to the fetal pig from its mother (blue tube)
umbilical arteries: the arteries carry wast from the fetal pig (red tube)
8. Do both sexes have mammary papillae? Explain. male and female in females these become the nipples in witch the young feed off of, and in males the do not develope but are there
9. How many mammary papillae are present in the fetal pig? 7 and 1/2
10. Compare and contrast the fore limb and the hind limb of the pig to the fore limb and hind limb of the human. Include presence of joints and the movement of the limbs in your description.
The pig and the human limbs are very simmular, they both have an ankle, knee, hip, shoulder, elbow, and wrist. All these joints also proforme the same actions with the same range of motion
11. Compare and contrast the external anatomy of the clam, crayfish, starfish and pig. The only thing that these fore organisems have in comon is they all can proform locomotion in some way or another. However the structures are compleatly diffrent. ex. tube feet to limbs
