During the filling phase of micturition. At what bladder volume is the first urge to void felt?
Your Answer:
Correct Answer: 150ml
Explanation:Micturition is defined as a process of expelling urine from the body. It is caused by the reflex contraction of detrusor muscle. Urinary bladder is a hollow muscular organ which can store 400-600ml of urine until it is expelled from the body. The first urge to urinate is felt when the bladder is filled with around 150ml of urine. The reflex action is initiated when the stretch receptors located in the bladder wall are stimulated. The afferent fibres pass to the pelvic splanchnic nerves to the 2nd, 3rd, and 4th sacral segments and some pass through the hypogastric plexus to the first and second lumbar segments of the spinal cord. Efferent pathways from the 2nd, 3rd, and 4th sacral segments leave the cords and through the splanchnic nerves and inferior hypogastric plexus supplies the smooth muscle of the bladder i.e. detrusor muscle. Detrusor muscle contracts and the sphincters are relaxed.

Regarding the female breast how many lobes does the typical breast contain?
Your Answer:
Correct Answer: 15-20
Explanation:The basic components of the mammary gland are the alveoli. These are lined with milk-secreting cuboidal cells surrounded by myoepithelial cells. The alveoli join to form groups known as lobules. The lobules form lobes. Each lobe has a lactiferous duct that drains into openings in the nipple. Each breast typically contains 15-20 lobes.

Your Answer:
Correct Answer:
Explanation:Contracted pelvis occurs when one or more of its diameters is reduced so that it interferes with the normal mechanism of labour. A transverse diameter below 11 cm will result in difficult delivery of the foetus and C-section will be the better option in that case

Which nerves innervate the internal anal sphincter?
Your Answer:
Correct Answer: Pelvic Splanchnic
Explanation:The anal sphincters are responsible for closing the anal canal to the passage of faeces and flatus. The smooth muscle or involuntary internal sphincter sustains contraction to prevent the leakage of faeces between bowel movements and is innervated by the pelvic splanchnic nerves, which are a branch of the spinal segment 4. The external sphincter is made up of skeletal muscle and can therefore contract and relax voluntarily. Its innervation comes from the inferior rectal branch of the pudendal nerve, and the perineal branch of S4 nerve roots.

Which structure reinforces the inguinal canal anterolaterally?
Your Answer:
Correct Answer: Internal oblique
Explanation:The anatomy of the inguinal canal is of surgical importance. In the male, the inguinal canal carries the spermatic cord, ilioinguinal nerve and important blood vessels, while in females the inguinal canal holds the round ligament, ilioinguinal nerve and blood vessels. The floor of the inguinal canal is made of the inguinal ligament (a thickened portion of the inguinal ligament), while the posterior wall is made of the transversalis muscle. The anterior wall is made of the external oblique aponeurosis, and the roof is made up of fibres of the internal oblique, transversus abdominis and its aponeurosis, and the conjoint tendon. This means that the anterolateral support structure of the inguinal canal would be the fibres of the internal oblique.

Regarding the pelvic outlet, what structure marks the posterior boundary?
Your Answer:
Correct Answer: Tip of the coccyx
Explanation:The bony pelvis is made up of a girdle with a central canal. The rim that surrounds the upper opening of the canal is called the pelvic inlet, while the lower rim is the called the pelvic outlet. The pelvic outlet is diamond-shaped and is bounded posteriorly by the tip of the sacrum, and anteriorly by the pubic symphysis, with its lateral boundaries being the ischial tuberosities and the sacrotuberous ligament.

Regarding the Pituitary gland which of the following statements is true?
Your Answer:
Correct Answer: It is surrounded by the sella turcica
Explanation:The Sella turcica is composed of three parts:
1. The tuberculum sellae (horn of saddle): a variable slight to prominent median elevation forming the posterior
boundary of the prechiasmatic sulcus and the anterior boundary of the hypophysial fossa.
2. The hypophysial fossa (pituitary fossa): a median depression (seat of saddle) in the body of the sphenoid that accommodates the pituitary gland (L. hypophysis).
3. The dorsum sellae (back of saddle): a square plate of bone projecting superiorly from the body of the sphenoid.
It forms the posterior boundary of the Sella turcica, and its prominent superolateral angles make up the posterior clinoid processes. -

Sensory supply to the clitoris is via branches of which nerve?
Your Answer:
Correct Answer: Pudendal nerve
Explanation:The pudenal nerves has three branches, namely the inferior rectal, perineal and the dorsal nerve of the clitoris. The perineal nerve has two branches: The superficial perineal nerve gives rise to posterior scrotal or labial (cutaneous) branches, and the deep perineal nerve supplies the muscles of the deep and superficial perineal pouches, the skin of the vestibule, and the mucosa of the inferior most part of the vagina. The inferior rectal nerve communicates with the posterior scrotal or labial and perineal nerves. The dorsal nerve of the penis or clitoris is the primary sensory nerve serving the male or female organ, especially the sensitive glans at the distal end.

Regarding the rectus sheath which of the following statements are true?
Your Answer:
Correct Answer: Above the arcuate line the internal oblique divides into two lamellae

Regarding the urinary bladder, what type of epithelium lines it?
Your Answer:
Correct Answer: Transitional
Explanation:The urinary bladder, and most of the urinary structures are lined by epithelium called the urothelium, or the transitional epithelium.
