spleen vasculature

splenic artery (CT) and splenic vein

10

spleen innervation

coeliac plexus

11

gut sections and general vasculature and innveration

foregut, oesophagus to major duodenal papilla (coliac axis and greater S)
midgut, MDP to 2/3rd way along transverse colon (SMA, lesser S)
hindgut, distal 1/3rd transverse colon to upper part of anal canal (IMA and least S)

12

testes and epididymis vasculature and innervation

testicular artery, vein and plexus

13

testes and epididymis lymph drainage

paired lumbar and preaortic nodes at L1 level

14

seminal vesicles vasculature and innervation

internal iliac artery branches (inferior vesicle, internal pudendal and middle rectal)
sympathetic innervation

15

prostate gland vasculature and innervation

prostatic arteries and venous plexus
inferior hypogastric plexus (sympathetic, parasympathetic and sensory)

16

scrotum vasculature and innervation

anterior and posterior scrotal arteries. Scrotal veins
genitofemoral branch, anterior and posterior scrotal nerves

17

describe lymph drainage of mammary glands

axillary nodes (75%)
parasternal nodes (20%)
posterior intercostal nodes (5%)

18

which nerves supply mammary glands

4th-6th intercostals

19

what goes through hilum of lung?

bronchus
pulmonary artery
2 pulmonary veins
bronchial vessels
pulmonary plexus of nerves and lymphatic vessels

20

describe innervation of larynx

recurrent laryngeal supplies motor to all muscles except cricopharyngeal which is supplied by external superior laryngeal. Internal superior laryngeal supplies sensation to larynx.

21

describe sinus drainage

all sinuses drain into middle meatus except sphenoid which drains into spheno-ethmoidal recess

22

what drains into the inferior meatus

lacrimal ducts and eustuchian tube

23

which structures pass through diaphragm and where

IVF and right phrenic T8
Oesophagus and vagus T10
Aorta, zygous vein and thoracic duct T12

24

what makes the upper oesophageal sphincter?

cricopharyngeus

25

what info travels through the cerebellar peduncles?

superior (purkinji) inhibition output to pons midbrain and cerebrum
middle, pons telling cerebellum what voluntary movements are happening
inferior, proprioception, balance info

26

carotid sheath contents

common and internal carotid artery, IJV, vagus

27

what are the infrahyoid muscles

-sternohyoid (C1-C3)
-omohyoid (C1-C3)
-thyrohyoid (C1)
-sternothyroid (C1-C3)
-all depress hyoid

28

lesser T10-T11
least T12

31

describe innervation of pharyngeal muscles

all constrictors, palatopharyngeus and salpingopharyngeus by vagus. Stylopharyngeus by glossopharyngeal.

32

uterus ligaments

broad, maintains position
round, maintain anterverted position
ovarian, joins ovaries to uterus

33

bladder vasculature

internal iliac artery branch, vesicle venous plexus

34

ureter vasculature

abdominal- renal and testicular/ovarian artery
pelvic- superior and inferior vesical arteries

35

knee joints

-tibiofemoral (medial and lateral condyles of femur), weightbearing
-patellofemoral (anterior and distal part of femur), allows quadriceps femoris to be inserted directly over the knee
-both lined with hyaline cartilage

36

knee ligaments

1) patellar
2) collateral
-medial, makes up joint capsule
-lateral
3) cruciate, 2 which cross over eachother
-anterior, prevents anterior dislocation of tibia onto femur
-posterior, prevents posterior dislocation of tibia onto femur

37

menisci function

-deepen articular surface of tibia to increase stability
-shock absorbers
*when ACL is taut your lateral menisci rotates
