Animal Science 434 - Male Anatomy
Objectives:
- Examine and learn the anatomical parts of the male reproductive tract. You will dissect either the bull or boar tract.
- Connect structure with function for the different parts of the male reproductive tract.
- Learn how the bull is similiar yet different from other species.
- Identify sperm from teh epididymis.
- Learn about Brucellosis, its diagnosis and prevention.
- Utilize statistics.
- Be sure you know your cow for the cow project and lab sections protocols and dates to implement outside of class.
- Select your mexico project and learn how to use electronic translation software.
Terminology:
- excurrent duct system - the vas efferentia, epididymis and vas deferens
- castration - removal of the testes in the male or ovaries in female
- cryptorchidism - when the testis fail to descend into the scrotum
- scrotum - a sac consiting of skin, sweat glands, a layer of smooth muscle (tunica dartos) and connective tissue that houses the testis
- inguinal hernia - when the adominal contents pass through the inguinal canal and enter the vaginal cavity (space between tunica vaginalis parital and visceral)
- gubernaculum - connective tissue that connects the testis and scrotum (specifically the tunica vaginalis parietal to epididymis/testis)
Laboratory Activities:
- Get ready for lab: You will review male anatomy in several species and view videos of the bull reproductive tract anatomy.
- Anatomy - First do the bull or boar dissection and then you can do the stallion. View any tracts you do not dissect either in class or via the on-line material below.
- Bull anatomy: You wll dissect a bull reproductive tract and identify the different anatomical parts.
- Boar Anatomy: You will dissect a boar reproductive tract and identify the different anatomical parts.
- Stallion: You will dissect a stallion reproductive tract and identify the different anatomical parts. Includes quizes on the stallion anatomy.
- Diagrams: To enhance your ability to remember what you have just observed in the dissection, you will draw a diagram of the bull reproductive tract.
- Species differences: Examine how male anatomy varies among species.
- Structure and Function: Connect the structure with the function and how this affects physiological differences among species.
- Epididymal Sperm: Prove sperm are present in the tail of the epidymis.
- Brucellosis: Examine the consequences and prevention of this disease.
- Statistics: Examine the results of lab 1 statistical excersice. What can we learn?
- Mexico Project: You will select your project topic.
