3. What is the length of a pigs birth cycle in pigs? How does this compare to humans?

• Although the number of piglets born will increase if mating is postponed, The results from a number of research trials comparing litter size after mating. Pregnancy rates were 69.6% for animals bred at first estrus and 77.4% when a high proportion of aborted human fetuses but not in those from domesticated mammals.

4. Which is more distal to the elbow- the wrist or the hoof?

• Distal is away from the center of body trunk or point of attachment. The wrist is farther away from center of body trunk.

5. Post a picture of the pig and give the orientation using the following terms, anterior, posterior, dorsal , and ventral.

The tail is posterior to the umbilical cord.
The lungs are ventral to the spine. 

The Heart is anterior to the kidneys.
The Spleen is dorsal to the stomach.

3. The length of a pigs menstral cycle is 21 days. Usually a human woman's menstral cycle lasts genarally a week. 

4. The hoof is the most distal from the elbow. 

5. 

The ears are anterior to the snout. The anus is posterior to the tail. The tail is dorsal to the umbilical cord. The umbilical cord is ventral to the spine. 

Pig Post #1 Dissection of the Fetal Pig (Ronjae and Saiswan )

1. All mammals have vertebrates, they are endothermic, produce milk, and have hair on their skin.
2. A domestic pig and a wild hog are from the same family which is the Suidae family. They have the same internal structure. However the domestic pig have a longer life span than the wild hog due to the hunting of wild hogs.
3. A pig is pregnant for 112-115 days. Humans are pregnant for 10 months.
4. The hoof is more distal to the elbow.

Questions

1. What are some characteristics shared by all mammals?

Some characteristics shared by all mammals are hair and mammary glands. They also have a single dentary bone called the mandible. 

2.  How are domestic pigs related to wild hogs found in some states?

Domestic pigs live longer but dont live that long because they get turned into food first. Hogs and pigs are from the same family group: Artiodactyla. 

3. What is the length of a pigs birth cycle in pigs?  How does this compare to humans? The pigs birth cycle is 112-115 days long. A human's birth cycle is 9 months long which is way longer than a pig's. 

4.  Which is more distal to the elbow- the wrist or the hoof?

The wrist is more distal to the elbow. 

5.  Post a picture of the pig and give the orientation using the following terms, anterior, posterior, dorsal , and ventral.

The snout is anterior to the heart.

The spine is posterior to the lungs.

The kidney is dorsal to the heart.

The diaphgram is inferior to the lungs.
