bronchus
pulmonary artery
2 pulmonary veins
bronchial vessels
pulmonary plexus of nerves and lymphatic vessels
20
Q

describe innervation of larynx

A

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

21
Q

describe sinus drainage

A

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

22
Q

what drains into the inferior meatus

A

lacrimal ducts and eustuchian tube

23
Q

which structures pass through diaphragm and where

A

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

24
Q

what makes the upper oesophageal sphincter?

A

cricopharyngeus

25
Q

what info travels through the cerebellar peduncles?

A

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

26
Q

carotid sheath contents

A

common and internal carotid artery, IJV, vagus

27
Q

what are the infrahyoid muscles

A
  • sternohyoid (C1-C3)
  • omohyoid (C1-C3)
  • thyrohyoid (C1)
  • sternothyroid (C1-C3)
  • all depress hyoid
28
Q

what are the suprahyoid muscles?

A
  • stylohyoid (mandibular branch of facial)

- mylohyoid (CN Vi)

29
Q

what is the contents of anterior triangle of neck

A

common carotid
internal and external carotids
IJV
CN VII, IX, X, XI, XII

30
Q

what are the spinal roots of the splanchnic nerves

A

greater T5-T9
lesser T10-T11
least T12

31
Q

describe innervation of pharyngeal muscles

A

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

32
Q

uterus ligaments

A

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

33
Q

bladder vasculature

A

internal iliac artery branch, vesicle venous plexus

34
Q

ureter vasculature

A

abdominal- renal and testicular/ovarian artery

pelvic- superior and inferior vesical arteries

35
Q

knee joints

A
  • 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
Q

knee ligaments

A

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
Q

menisci function

A
  • deepen articular surface of tibia to increase stability
  • shock absorbers
  • when ACL is taut your lateral menisci rotates
38
Q

which muscles does the median nerve innervate in the hand

A 
LLOAF
Lateral Lumbricals
Opponens Pollicis
Abductor pollicis brevis
Flexor pollicis brevis
39
Q

joints of ankle

A

tibiotalar - dorsiflexion and plantarflexion

subtalar (talus and calcaneus) - inversion and eversion

40
Q

what does the sciatic nerve divide into?

A 
tibial
common perineal (further divides into deep and superficial)
41
Q

which nerves supply the thigh compartments

A

posterior - sciatic
medial - obturator
anterior - femoral

42
Q

which nerves supply the leg compartments

A

posterior - tibial
lateral - superficial perineal
anterior - deep perineal

43
Q

general innervation of arm

A

anterior - musculocutaneous

posterior - radial

44
Q

general innervation of forearm

A

anterior - median

posterior - radial

45
Q

general action of lower limb

A

glutes - extend and abduct hip and femur
ant. thigh - flex femur at hip
med thigh- adduct femur
post thigh - extend hip and flex knee
post leg - plantar flexion, flex toes, invert foot
lat leg - evert foot
ant leg - dorsiflexion, entend toes invert foot
