Correct Answers | 100% Pass
Function of the Urinary Bladder - ANSWER -Storage of urine
Structure of the Urinary Bladder - ANSWER -1. Mucosal Layer
2. Submucousal Layer
3. Muscular Layer
4. Serous Layer
Mucosal Layer of the Urinary Bladder - ANSWER -Transitional epithelium
Submucousal Layer of the Urinary Bladder - ANSWER -Connective Tissue with
increased number of elastic fibers
Muscular Layer of the Urinary Bladder - ANSWER -Interlaced smooth muscle
form the detrusor muscle and internal urethral sphincter.
Involuntary muscle.
Serous Layer of the Urinary Bladder - ANSWER -Parietal peritoneum.
Superior surface of the urinary bladder ONLY
Function of the Urethra - ANSWER -Convey urine from bladder to expulsion and
carry semen.
Structure of the Urethra - ANSWER -1. Mucosal Layer
2. Muscular Layer
Muscular Layer of the Urethra - ANSWER -Smooth muscle.
Important in ejaculation.
Micturition - ANSWER -Bladder stretch receptions cause urination reflex and:
1. Contraction of detrusor
2. Relaxation of internal sphincter
,Flow restricted by contraction of external urethral sphincter (skeletal muscle).
PATHOLOGY NOTE:
Enuresis & Nocturnal Enuresis - ANSWER -Young children may lack unconscious
control of the external sphincter resulting in enuresis.
Common at night, known as nocturnal enuresis.
More common in ADD/ADHD children.
PATHOLOGY NOTE:
Incontinence - ANSWER -Incontinence is the loss of micturition control (urinary
output).
Caused by spill cord damage, pregnancy, obesity, age or pathology, e.g., enlarged
prostate.
PATHOLOGY NOTE:
Urinary Incontinence (SUI) - ANSWER -Inability of the urethra/sphincter to
properly regulate outflow of urine from bladder due to stretching (stress) of the
pelvic flow muscles and stretching of the connective tissue between the bladder
and vagina.
Life Span Changes in regards to the Urinary System - ANSWER -1. Kidney cells
decrease numbers
2. Glomeruli numbers decrease
3. Fats deposit in tubules decrease absorption
4. Renal blood flow decreases
5. Bladder loses elasticity, resulting in decreased volume (due to collagen fibers
building up)
6. Urge to urinate delayed until last moment
Function of the Male Reproduction System - ANSWER -Production and discharge
of sperm, copulation (insertion of penis into vagina)
What are the components of the Male Reproduction System - ANSWER -1. Testes
2. Epididymis
3. Vas (Ductus) Deferens
, 4. Seminal Gland (Vessicle)
5. Prostate Gland
6. Bulbourethral Glands
7. Scrotum
8. Penis
Functions of the Testes - ANSWER -Production of sperm cells and testosterone
Function of the Seminiferous Tubules - ANSWER -Site of production of sperm
cells from puberty until death.
Function of Sperm Cell - ANSWER -Carry male's chromosomes
Components of the Sperm Cell - ANSWER -1. Head
2. Midpiece
3. Tail (Flagellum)
Head of a Sperm Cell - ANSWER -Nucleus with chromosomes (23)
Midpiece of a Sperm Cell - ANSWER -Mitochondria
Spermatogenesis - ANSWER -Production of sperm cells
PATHOLOGY NOTE:
What can give rise to testicular cancer in young males? - ANSWER -Epithelial
cells of the seminiferous tubules can give rise to testicular cancer in young males.
Function of the Epididymis - ANSWER -Nutrition and maturation of sperm
How long can sperm live once mature? - ANSWER -Sperm can live for 2-3 weeks
once mature.
Function of the Vas (Ductus) Deferens - ANSWER -Transport sperm to
ejaculatory duct.
