Q

What does the pectinate line separate?

Study These Flashcards
A

Soma from viscera

25
Describe the lesions below the pectinate line
Painful
26
Describe the lesions above the pectinate line?
Silent *unless they distend the gastrointestinal wall
27
What does the bulbospongiosus muscle cover?
The bulb of the penis *helps expel contents of the spongy urethra
28
What does the ischiocavernosus muscle cover?
Covers the crus of the penis *Helps maintain erection
29
What are the three parts of the male urethra?
Prostatic urethra Membranous urethra Spongy urethra
30
What does the internal urethral sphincter do?
Prevents semen from entering the urinary bladder
31
What does the deep artery of the penis do?
It is a source of blood that engorges the corpus cavernous to from an erection
32
What is peyronie’s Disease?
Idiopathic formation of fibrous plaques within the tunica albuginea
33
What does the greater vestibular gland do?
Secrete mucus to lubricate vaginal canal
34
Activation of the sympathetic division does what to the gastrointestinal system?
1. Vasoconstriction of blood vessel supplying the gut 2. Promotes peristalsis and digestion
35
Activation of the parasympathetic division does what to the gastrointestinal system?
1. Vasodilation blood vessels supplying to gut 2. Promotes peristalsis and digestion
36
What are the pregnglionic neuronal cell bodies of the sympathetic division?
T1-L2 Spinal cord
37
What are the pregnglionic neuronal cell bodies of the parasympathetic division?
S2-S4 Brain stem
38
What are the preganglionic axons to the foregut and midgut from the brain stem? (Parasympathetic division)
vagus nerve (X)
39
What are the preganglionic axons to the hindgut from the s2-s4 spinal cord? (Parasympathetic division)
Pelvic splanchcic nerve
40
What is the neurotransmitter of the parasympathetic division of the gastrointestinal system?
Acetylcholine
41
Where are the postganglionic neuronal cell bodies of the parasympathetic division located?
In the gut wall
42
What is Hirschsprung disease?
Failure of migration of neural crest cells *Will be a lack of peristalsis and functional obstruction
43
What are the two sets of ganglia for the postganglionic sympathetic neurons? (Cell bodies)
1. Sympathetic chain ganglia (skin, sweat, ar rector pill muscles) 2. Pre-aortic sympathetic ganglia (Abdominal organs)
44
Where are the preganglionic sympathetic axons distributed to?
Pre-aortic ganglia via splanchnic nerves
45
Describe the sympathetic pathway innervation starting with T5-T9
Spinal cord level of preganglionic cell bodies: T5-T9 Splanchnic nerve carrying preganglionic axons: Greater ganglion containing postganglionic neuronal cell bodies: Celiac Artery carrying postganglionic axons: Celiac Target: Foregut
46
Describe the sympathetic pathway innervation starting with T10-T11
Spinal cord level of preganglionic cell bodies: T10-T11 Splanchnic nerve carrying preganglionic axons: Lesser ganglion containing postganglionic neuronal cell bodies: Superior Mesenteric Artery carrying postganglionic axons: Superior Mesenteric Target: Midgut
47
Describe the sympathetic pathway innervation starting with T12
Spinal cord level of preganglionic cell bodies: T12 Splanchnic nerve carrying preganglionic axons: Least ganglion containing postganglionic neuronal cell bodies: Aorticorenal Artery carrying postganglionic axons: Renal Target: Kidney
48
Describe the sympathetic pathway innervation starting with L1-L2
Spinal cord level of preganglionic cell bodies: L1-L2 Splanchnic nerve carrying preganglionic axons: Lumbar ganglion containing postganglionic neuronal cell bodies: Inferior mesenteric Artery carrying postganglionic axons: Inferior mesenteric Target: hindgut
49
Describe secondary visceral pain
Inflammation from diseased organs spreads to the immediately adjacent parietal peritoneum *innervated by somatic nerves
50
What are the abdominal regions of visceral pain afferents
Target———-Region Foregut=Epigastric Midgut=Umbilical Kidney=Costovertebral angle Hindgut=Hypogastric/ pubic
51
What does a positive Murphy sign indicate?
Gallbladder disease *Tenderness at the intersection between costal margin and lines semilunaris
52
What does a positive Kehr’s sign indicate?
Splenic rupture *Dermatomes C3-C5 (left shoulder)
53
Where can gallbladder pain be referred to?
The right shoulder *Due to the contact with parietal peritoneum on the diaphragm (innervated by phrenic nerve C3-C5)
54
What is McBurney’s point?
One-third distance form the ASIS to umbilicus *Where the appendix is located *possible appendicitis
55
Where can a kidney stone get stuck?
1. Passing from renal pelvis to ureter (T11-T12 dermatomes) 2. As the ureter passes over the pelvic brim (Lumbar region) 3. As the ureter enters the urinary bladder (inguinal and hypogastric regions)
56
What happens to the urinary system during parasympathetic activation?
Erection (Parasympathetic=Points)
57
What happens to the urinary system when sympathetic division gets activated?
Emission (Sympathetic=Shoots)
58
What are the four components of the Inferior hypogastric plexus?
1. Hypogastric nerve 2. pelvic splanchnic nerve 3. Sacral splanchnic nerve 4. Visceral afferents traveling with all of these nerves
59
What nerves produces an erection?
Cavernous Nerves
