Flashcards in Lab 11:Fetal Pig Dissection Deck (45):
1

Pigs are born with closed_____

Eyelids

2

The external ear flap.

Pinna

3

Exterior openings of the nose used for breathing and the sense of smell.

External nares

4

The long, stiff hairs on the head, commonly called whiskers. Function is touch

Vibrissae

5

These are the toes and hooves.

Digits

6

There are 5 to 5 pairs of these structures present in both sexes, but develop into the mammary glands in only females.

Mammary papilla

7

Contains the 2 umbilical arteries and one umbilical vein. It serves as the connection between the fetus and the fetal placenta.

Umbilical cord

8

Female's external genitalia

Genital papilla

9

The opening which is the terminal end of the male urogenital tract

Urogenital Opening

10

A sac of skin beneath the tail containing the male's testes.

Scrotum

11

This structure is the terminal opening of the digestive tract

Anus

12

A large salivary gland which lies posteriorly and ventrally to the masseter muscle

Parotid gland

13

This salivary gland is small and has an oval shape. It lies partially ventral to the parotid gland, and between the parotid and the angle of the jaw, AKA submaxillary gland.

Mandibular gland

14

This salivary gland is narrow and flat. It lies beneath the skin, medial to the lower jaw, and alongside the tongue

Sublingual gland

15

This endocrine gland is large, and elongated. It lies beneath the skin on each side of, and over, the trachea. Hormones stimulate the early development of the immune system.

Thymus gland

16

This small endocrine gland is darkly colored, and has an oval shape. Lies between the two lobes of the thymus gland, posterior to the larynx, and ventral to the trachea.

Thyroid gland

17

This is the ridged surface which forms the anterior portion of the roof of the mouth.

Hard palate

18

This is the smooth surface which forms the posterior portion of the roof of the mouth.

Soft palate

19

This structure lies on the floor of the mouth, between the lower jaws. Location of taste buds.

Tongue

20

These are the small projections on the tongue, They are particularly large on the anterior margins and the base of the tongue. Aid in food manipulation.

Papillae of the tongue

21

This is the region of the throat where the oral and nasal cavities join

Pharynx

22

This structure is a flap of skin which covers the glottis. It serves to separate the esophagus from the trachea and prevent food or liquid from entering the trachea.

Epiglottis

23

This is the hole that is the opening of the trachea. It is covered by the epiglottis.

Glottis

24

This tube is commonly called the windpipe. It is a tube extending from the larynx in the throat to the lungs.

Trachea

25

This structure is commonly called the voice box. It connects to the glottis anteriorly, and the trachea posteriorly. Contains the vocal chords..

Larynx

26

These are the large organs that function in gas exchange. Lie on the lateral sides of heart.

Lungs

27

This is a part of the lung. Commonly known as the lung root and is the only part of the lung attached to the body.

Hilus

28

This is the skeletal muscle located between the lungs and the liver, It is the primary muscle responsible for breathing

Diaphragm

29

The tube connecting the pharynx to the stomach,

Esophagus

30

This digestive organ lies posterior to the liver

Stomach

31

A sheet of connective tissue which attaches to and anchors the inside convex curve of the stomach.

Lesser omentum

32

A sheet of connective tissue which attaches to and anchors the outside concave curve of the stomach

Greater omentum

33

A doughnut like smooth muscle, found at the posterior end of the stomach. Separates the stomach from the duodenum.

Pyloric sphincter muscle

34

This structure is a sac containing green bile, located underneath and attached to the middle lobe of the liver.

Gall bladder

35

The duct which transports bile to the duo duodenum.

Common bile duct

36

This is the largest gland in the body, located between the stomach and diaphragm. Reddish brown color.

Liver

37

This organ is a long, flat,finger like projection to the right of the stomach. Functions to store blood. Dark red to purplish in color

Spleen

38

An organ which has a right and left lobe, and produces digestive enzymes. Right lobe is beside the pyloric sphincter, at base of the stomach

Pancreas

39

The anterior portion of the small intestine, just posterior to the stomach

Duodenum

40

The portion of the digestive system between the stomach and the large intestine.

Small Intestine

41

This is the sheet of connective tissue attached to the intestines.

Mesentery

42

This structure is a finger like projection of the large intestine at the junction of the large and small intestines.

Cecum

43

The intestine posterior to the cecum.

Large intestine

44

The most posterior portion of the large intestines that descends along and ventral to the vertebral column

Colon
