24
Q

What spinal levels are the pudendal plexus?

A

parts of S2 and S3, and all of S4

25
The [dorsal/ventral] primary ramus innervates the skin and muscles around the spine
Dorsal
26
The [dorsal/ventral] primary ramus innervates the skin and muscles for the rest of the body.
Ventral (lat/ant trunk, UEs and LEs)
27
As they exit the vertebral column, the dorsal and ventral roots join to form..
the spinal nerve (a mixed nerve)
28
The spinal nerve then divides into..
into a posterior (dorsal) primary ramus and an anterior (ventral) primary ramus
29
extension of pia mater
Film terminale
30
filum terminale fuses with dura mater and attaches to coccyx
Coccygeal ligament
31
Name the meninges layers from superficial to deep
1. Dura mater 2. Acrachnoid membrane 3. Pia mater
32
meninges, tough outer layer; wraps around filum terminale
dura mater
33
meninges, shaped like a spider; fuses with dura mater at S2
Arachnoid membrane
34
attached to the nervous system itself (brain or spinal cord); innermost layer
Pia mater
35
gross anatomy in the spinal cord, thicker than surrounding regions; adding a lot of cells from lower (lumbar) and upper extremity
``` Cervical enlargement (C4-T1) Lumbar enlargement (T11-S1) ```
36
the tapered, lower end of the spinal cord
Conus medullaris (near L1 and L2)
37
Which part of the superficial fascia is the fatty, superficial layer?
Camper's (only occurs in pubic region)
38
Which part of the superficial fascia is the deep fibrous layer?
Scarpa's fascia
39
Name the m layers of the abdominal wall from superficial to deep
1. External oblique muscle 2. Internal oblique muscle 3. Rectus abdominis 4. Transverse abdominal muscle 5. Pyramidalis muscle
40
What abdominal regions are above the subcostal plane? what level is the subcostal plane?
Right hypochondriac, epigastric, left hypochondriac; | L3
41
What abdominal regions are below the transtubercular plane? what level is the transtubercular plane?
Right ilioinguinal, hypogastric, left ilioinguinal; | L5
42
What abdominal regions are in between the subcostal and transtubercular plane?
Right lumbar, umbilical, and left lumbar
43
What plane of the abdominal region are lines dropped straight down through the middle of the clavicle?
Midclavicular planes
44
Identify the superior border of the anterior abdomen.
Diaphragm, 7 – 10 ribs, xiphoid process, intersternal notch, costal margins of the arch
45
Identify the inferior border of the anterior abdomen.
Abdomen and pelvic region, starts at iliac crest, ASIS, inguinal ligament, pubic tubercle and crest.
46
hernia follows path from deep ring to canal to superficial ring; occurs through a weakness in the internal inguinal ring (deep inguinal ring); deep inguinal ring is a little bit open and the structures of deep abdominal cavity can potentially exit through the superficial inguinal ring; follows a passageway –not directly exiting through the wall
Indirect hernia
