Which side of the bladder is covered by peritoneum?
Only the superior surface
The bladder wall muscle is called the
Involuntary opening of the urethral sphincter is controlled by the
stretch receptors of the detrusor muscles
3 sections of the male urethra are
Prostatic, Membranous & Penile/Spongy Urethra
Urination reflex involves which ANS system?
Reflex distention of the bladder activates stretch receptors which travel to the micturition center of the spinal chord (S2-S4) activating the
parasympathetic motor neurons of the detrusor muscle causing contraction of the detrusor muscles, which will relax the internal urethral sphincter, causing a decrease in somatic signals, & thus relaxing the external urinary sphincter
In voluntary micturition, the stretch receptors send info to the
only by CN-9, for gen. sensations (touch & temp.) & taste!
The posterior tongue lies within the
The palates separate the oral cavity from the
nasal cavity & the nasopharynx
The largest salivary gland is innervated by
CN-9 (glossopharyngeal)The Parotid Gland
The submandibular/submaxillary gland is innervated by
CN-7 (Facial Nerve)
The sublingual gland is innervated by
CN-7 (Facial Nerve)
The dilated superior part of the stomach (related to the left dome of the diaphragm) is the
The superior “dip”/notch in the stomach, is called the
The body of the stomach lies between the
fundus & pyloric antrum
The pyloric antrum is
the widened funnel shaped area that leads into the pyloric canal (narrow part)
The thickned distal region of the pyloric canal forms the
Pyloric Sphincter, which controls discharge of stomach contents through the pyloric orifice into the duodenum
The concave border of the stomach is called the
The convex border of the stomach is called the
Plicae Circulares are
shelf-like folds that are formed from modified version of the mucosa & Submucosa.
The shortest, widest & most fixed part of the small intestine is the
The duodenum is covered by
mesentery for the first 2cm of the superior part & the remaining superior part plus the next two parts are retroperitoneal, where the final limb where it joins the jejunum & becomes intraperitoneal again.
The MAJOR DUODENAL PAPILLA is
where the pancreatic duct & the common bile duct empty bile & enzymes into their long duodenum; it also marks the end of the foregut!
The part of the large intestine in the lower right quadrant, which has the appendix, is the
The ascending colon runs from the cecum to the right lobe of the liver, where it then becomes the
Right Colic Flexure, or Hepatic Flexure
The Right Colic/Hepatic Flexure is separated from the anterior abdominal wall by the
The Transverse colon runs across the abdomen & through the left colic flexure, then becoming the
The descending colon is (peritoneal location)
The descending colon & the rectum are linked by the
Which pelvic ligament has a lateral attachment at the ischial tuberosity?
What foramen is in between the sacrospinous (inferior to) & sacrotuberous ligaments?
Which foramen is superior the sacrospinous ligament?
What divides the greater sciatic foramen into 2 parts?
What passes above the Piriformis in the greater sciatic foramen?
Superior gluteal nerves, arteries & veins
What passes below the Piriformis in the greater sciatic foramen?
Inferior gluteal nerves + vessels, sciatic nerve, pudendal nerve, the internal pudendal vessels, posterior femoral cutaneous nerves, and the nerves to the Obturator internus, quadratus femorus and superior + inferior gemellus muscles.
What nerve exits from the lesser sciatic foramen?
pudendal nerve (but it goes back into perineum)
Actions of the Gluteus maximus, medius and minimus muscles are
extension & lateral rotation of the thigh.
Besides the gluteus max, med, min, all other gluteal muscles aid in
