Flashcards in Male Macrostructure Deck (18)
The male sex hormone that is responsible for the development of secondary male characteristics and sex behavior (libido)
A protective fibrous sheath consisting of smooth muscle, blood vessels, and nerves
Primary muscle supporting testes and coursing the length of the spermatic cord
Sac outside the body cavity that protects and supports the testes
A coiled tube connected to each testis that is responsible for the maturation, storage, and transport of sperm cells.
Part of the spermatic cord that is the passageway for sperm from the epididymis to the urethra
Deferent duct (Vas deferens)
An enlargement of the deferent duct that opens into the urethra and may serve as a temporary storage
A passageway for both semen and urine that extends from the ampullae and bladder to the end of the Penis
Responsible for the production of secretions that contribute to the liquid non-cellular portion of semen known as seminal plasma
Paired accessory glands that secrete fluid that nourishes the sperm and provides protection and transportation medium for semen upon ejaculation
Vesicular glands (seminal vesicles)
Secrets thick, milky fluid that mixes with seminal fluid to provide nutrition and substance to the semen.
Secretes fluid that cleanses and neutralizes the urine residue that can kill sperm cells in the urethra
Bulbourethral glands (Cowper's glands)
The organ that allows for the deposition of semen into the female reproductive tract
Muscle that contracts to retract the penis form the sigmoid flexure amd relaxes to extend the penis upon sexual excitement
Retractor penis muscle
External portion of the male reproductive tract that serves to protect the penis from injury and infectiom
The process by which animals produce offspring for the purpose of continuing the species.
The major function of the male reproductive system:
- Production, storage, and deposition of sperm cells.
- Production of male sex hormones.
- Serves as passageway for expelling urine from the urinary bladder
