Jonathan Smeal, Emily Smith

Dorsal-back Ventral-bottom-stomach Anterior-front of body Posterior-back of body Pectoral- chest Pelvic- lower body Trunk- lumbar/ lower back Thorax- middle section of the body

Abdomen- the torso area Medial- middle or centre of body/ midline Caudal- toward tail Cranial- bones of the skull Umbilical cord- connects the embryo to the placenta. Mammary papillae- location of feeding for young

Proximal- lying near the point of reference Distal- lying further from the point of reference Lateral- side

Pinnae- outer ear Nictitating membrane- “third eyelid” transparent skin deep in the outer eyelids

Female urogenital opening- opening near the umbilical cord urogenital papillae- flap of skin above the anus

Male Scrotal sacs- male reproductive organ

Dissected unbilical Artery- red Vein- blue

7. Research and discuss the function of the umbilical veins and arteries(distinguish between the two). 8. Do both sexes have mammary papillae? 9. How many mammary papillae are present in the fetal pig? 10. Compare and contrast the limbs of the pig with the limbs of a human being.

7. the veins are blue and arteries are red. Also veins carry blood from the heart and arteries carry blood back to the heart.

8. Yes, both male and female have them.

9. There are 8

10. there are many differences in the limbs

=Mouth Anatomy=

Epiglottis-cartilage lidike appendage- used to cover glottis to prevent unwanted objects going down the throat

Glottis-vocal apparatus of the larynx- contains vocal cords and openings between them

Gullet-the tube by which food and water is carried to the pharynx-

Nasopharynx-found at the back of the mouth, part of the pharynx going from the posterior nares –carries air from the nasal chamber to the trachea

Soft palate-muscular part of the roof of the mouth, directly behind the hard palate lacks bone

Hard palate-bony part of the roof and mouth in front of palate

Nare – nostrils- used for breathing

Tongue-an organ on the floor of the mouth- used for sound making

Taste buds-flask shaped cell nests located on the tongue- used to taste

Vestibule- tooth surface

Uvula- central taglike structure hanging down from the soft palate

 * ~ Structure ||~ Description ||~ Function ||
 * = Parotid Gland ||= Largest of salvilary glands ||= Helps the pig swallow ||
 * = Submaxillary Gland ||= A salivary gland inside the lower jaw ||= Porduces nocturnal salica ||
 * = Wharton's Duct ||= Enclosed passage for conveying a liquid or gas ||= Drains saliva from the submandibular glands ||

3. The glottis, gullet and epiglottis are located very close to each other. Explain the relationship between the structure and the openings 4. Discuss the tongue and the location of the taste buds. 5. Which jaw (s) have teeth in the pig? When do teeth start erupting?

3. The glottis is the vocal

Chart of muscle types



Glossary

Joint- location where two or more bones make contact. Extensor-extends the medial four digits of the hand Flexor-strong fibrous gland that arches over the carpus Origin-starting point on something Insertion-a comparison Belly-digastric muscle, small muscle located under the jaw Tendon-tough band of fibrous tissues connecting muscles to the bone Fascia-soft tissue component Antagonistic pairs-muscles found in pairs Adductor-muscles of the hip, draws the limb to the plane of the body. Abductor-a movement that draws the limb away from the plane of the body.

=Digestive System=







5. it is divided into four lobes

6. the bile that is produced in the liver is carried to the gallbladder

7.the three parts of the small intestine are duodenum, jejunum and the ileum. the duodenum is where the food is broken down. the jejunum is where most of the nutrients are absorbed. the ileum absorbs the leftover nutrients that the jejunum doesnt absorb.

8.the pigs colon is in a ball the humans colon wove around abdominal cavity.

=Respiratory System= = =






 * Structure || Description || Function ||
 * Epiglottis || Small flap of skin || Flap of skin that covers the trachea ||
 * Vocal cord || A tube that allows sound waves to be emmited || Allow the pig to communicate ||
 * Trachea || Tube that carries air || The "windpipe" that transports air to the lungs ||
 * Bronchial tubes || Tubes that fallow after the trachea || Break off from the trachea and transports oxygen ||
 * alveoli || Small openings after the bronchial tubes || Exchange gasses ||

4.right lung has four lobes the apical, cardiac, diaphramatic and the intermediate. the left lung has three the it is missing the intermediate lobe.

5. the pig we had has two vocal cords.

=Circulatory System=







6. left ventrical is bigger because it pumps blood at a high pressure. 7.it is connected to the right ventrical and that is in the lower chamber in the right side. 8.the aorta is connected to the left ventrical 9.aorta is the largest artery in the body 10.arteries carry blood away from the heart. veins carry it to the heart.



=Urogenital System=





6. Why are reproductive and excretory systems studied together?

7. What is the main purpose of the excretory system?

8. What is the main purpose of the reproductive system?

9. Trace the path of luquid waste through the body of the pig to the external enviroment.

10. Trace the path of the eggs through the female reproductive system.

11. Trace the path of the sperm through the male reproductive system.

12. What system do the terms listed in numbers 1 and 4 belong to?

13. What system do the terms in numbers 2 and 3 belong to?

14. The adrenal gland is closely associated with the kidney. Describe, state the gland's function and list the system that the gland belongs to.
