Bladder neck closure and relaxation of the bladder is mediated by?
Your Answer: Sympathetic Fibres S2,S3,S4
Correct Answer: Sympathetic Fibres L1,L2
Explanation:The neck of the bladder is surrounded by the internal sphincter. It is supplied by the sympathetic and parasympathetic nerves of the splanchnic nerve. Parasympathetic stimulation causes the detrusor muscle to contract and the internal urethral sphincter to relax. It Is predominantly by the parasympathetic nerves S2-S4. Relaxation of the bladder is caused by inhibiting the sacral parasympathetic preganglionic neurons and exciting the lumbar sympathetic preganglionic neurons. Remember SYMPATHETIC is for STORAGE and PARASYMPATHETIC is for PEEING.

At the time of delivery, if there is a laceration of perineal body but not the anal sphincter, this type of laceration is classified as?
Your Answer: Second degree
Explanation:Perineal tears are common at the time of child birth. First degree perineal laceration means that the wound is so small that it doesn’t require any stitches and usually heals on its own. 2nd degree means that skin and smooth muscles are both torn. 3rd degree tear means that the tear is beyond the perineal muscles and the muscles surrounding the anal canal, while in 4th degree, the perineal tear goes through the anal sphincter up to the rectum.

During the filling phase of micturition. At what bladder volume is the first urge to void felt?
Your Answer: 500ml
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 Pituitary gland which of the following statements is true?
Your 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. -

The rectus sheath is formed by which of the following?
Your Answer: aponeuroses of transversus abdominis, external and internal oblique
Explanation:The rectus sheath is formed by the decussation and interweaving of the aponeuroses of the fl at abdominal muscles. The external oblique aponeurosis contributes to the anterior wall of the sheath throughout its length. The superior two thirds of the internal oblique aponeurosis splits into two layers (laminae) at the lateral border of the rectus abdominis; one lamina passing anterior to the muscle and the other passing posterior to it. The anterior lamina joins the aponeurosis of the external oblique to form the anterior layer of the rectus sheath. The posterior lamina joins the aponeurosis of the transversus abdominis to form the posterior layer of the rectus sheath.

The inguinal canal is reinforced posteriorly by which structure?
Your Answer: Conjoint tendon
Explanation:The Inguinal Canal
– Anterior wall: formed by the external oblique aponeurosis throughout the length of the canal; its lateral part is reinforced by muscle fibres of the internal oblique.
– Posterior wall: formed by the transversalis fascia; its medial part is reinforced by pubic attachments of the internal oblique and transversus abdominis aponeuroses that frequently merge to variable extents into a common tendon—the inguinal falx (conjoint tendon)—and the reflected inguinal ligament.
– Roof: formed laterally by the transversalis fascia, centrally by musculo-aponeurotic arches of the internal oblique and transversus abdominis, and medially by the medial crus of the external oblique aponeurosis.
– Floor: formed laterally by the iliopubic tract, centrally by gutter formed by the infolded inguinal ligament, and medially by the lacunar ligament. -

Which one of the following statements regarding the fetal head is true?
Your Answer: Is likely to be a vertex presentation when the head is deflexed
Correct Answer: Considered to be engaged when the biparietal diameter passes the level of the pelvic inlet
Explanation:The fetal head is engaged when the head of the foetus or the presenting part enters the pelvic inlet or pelvic brim. It usually occurs at 38 weeks of gestation.
The Spalding sign refers to the overlapping of the fetal skull bones caused by collapse of the fetal brain. It appears usually a week or more after fetal death in utero.
In brow presentation the scalp is deflexed as the foetus is looking upward. Normally the head is inflexed such that the chin is touching the chest. -
