Pharming

DEFINITION 5 Pharmaceuticals are produced in livestock Secreted in milk, blood, or urine for convenient collection

Xenotransplantation

Organs from some animals can be transplanted into humans Using organs from genetically engineered animals could prevent rejection by recipients TERM 7

Cloning

DEFINITION 7 Producing an identical twin TERM 8

Embryonic cloning

DEFINITION 8 Splitting embryos to produce two or more TERM 9

What is the process of Adult cloning somatic

cell nuclear transfer

DEFINITION 9 Remove the nucleus from an ovum of the same species Transplant the nucleus from an adult cell into the enucleated ovum (from animal to be cloned) Ovum with new genetic material develops as an embryo Transfer embryo into a recipient female Offspring is genetically identical to the donor of the nucleus TERM 10

When and who was cloning first successful?

DEFINITION 10 Dolly 1996

Cryptorchidism

The condition where testes dont descend out of the body Unilateral (one) or bilateral (both) cryptorchid Inhibits sperm production, but not testosterone production TERM 17

Epididymis (where is it located, what are its

functions?)

DEFINITION 17 Next to the testis within the scrotum Includes a head, body, and tail Major functions: Sperm storage Sperm maturation Sperm transport TERM 18

Vas deferens

DEFINITION 18 Primary function is sperm transport Vasectomy can be used for sterilization TERM 19

Urethra

DEFINITION 19 Passageway for semen and urine Extends through the end of the penis TERM 20

Accessory sex glands (What do they do?)

DEFINITION 20 Attached to the urethra in the pelvic area Add fluid volume, nutrients, buffers, and coagulation factors

What are examples of the accessory sex

glands? (Males)

Vesicular glands (seminal vesicles) Prostate gland Bulbourethral gland (Cowpers gland) TERM 22

Penis

DEFINITION 22 Organ of copulation TERM 23

Vascular penis

DEFINITION 23 Erection by enlargement and extension Present in stallions, dogs, and cats Dogs and cats also have a baculum or os penis (bone inside the penis that aids in copulation) TERM 24

Fibroelastic penis

DEFINITION 24 Erection primarily by extension Retractor penis muscle holds the relaxed penis in an S- shape called the sigmoid flexure Present in bulls, rams, boars, and bucks TERM 25

In poultry where is the Testis

located?

DEFINITION 25 Testes are contained within the body No temperature regulation is needed
