25
Temporal part of TMJ
does protraction/glide late opening upper joint
26
Mandible part of TMJ
rolls lower joint first part of opening
27
Soft palate
barrier between nasal and oral cavities
28
oral cavity proper
portion of mouth above the tongue
29
Hard palate
bone portion of the mouth that separates the oral cavity and nasal cavity
30
Tongue muscles
intrinsics = inside the tongue extrinsic = outside the tongue
31
Genioglossus
Extrinsic of tongue Chin
32
Palatoglossus
Extrinsic of tongue palate
33
Styloglossus
Extrinsic of tongue styloid process
34
Hyoglossus
Extrinsic of tongue hyoid bone
35
Submandibular gland
underneath the mandible
36
Parotid gland
along the ramus of the mandible
37
Parts of pharynx
Nasopharynx Oropharynx Laryngopharynx Connects to esophagus
38
Larynx
shortens to help widen the pharynx to allow more water/food in
39
Hyoid bone is at the same level as
C3
40
Where does the brachial plexus come through?
anterior and middle scalene
41
Parts of ear
Outer Middle Inner
42
Middle ear
Incus, Malleus, Stapes bones Ear drum
43
Inner Ear
Semicircular canals: balance Cochlea: hearing Saccule, Utricle = vestibular portions
44
Semicircular Canals
fluid within allows you to know where you are at in space
45
Thoracic Cavity
truncated cone narrowest superior = ribs slant down circumference increases inferiorly maximum size at abdominal floor made up by thoracic diaphragm
46
Thoracic Cage includes
ribs costal cartilages supported by sternum and thoracic vertebrae lower portion protects abdominal viscera bony portion of thoracic wall
47
Thorax
region between neck and abdomen contains organs of respiratory & cardiovascular system 3 main spaces = mediastinum, right & left pulmonary
48
Thoracic Wall
bony portion is thoracic cage muscles that extend between ribs skin, subcutaneous tissue, muscles, fascia
49
Thoracic Cage purpose
protection of vital thoracic and abdominal organs from ext forces resist negative internal pressures support for weight of upper limbs attachment of muscles to maintain UE position attachment of muscles of abdomen, neck, back, respiration
50
External intercostal does
inspiration
51
Internal intercostal does
forced expiration
52
Abdominal Walls
contract to increase area distend for accommodation contains peritoneum
53
Peritoneum
Serous memnrame reflects and continues onto abdominal viscera creates sac and peritoneal cavity
54
Abdominal Cavity
forms upper part of abdominopelvic cavity border is pelvic area extends to 4th intercostal space location of most digestive organs, part of urogenital
55
muscles relative to Rectus abdominis
External oblique = anterior Transversus abdominus = posterior Internal oblique = goes ant and post
56
Rotating to the left
R external oblique L internal oblique
57
Rotating to Right
L external oblique R internal oblique
58
After arcuate line...
all muscles (obliques & transverse) go ANTERIOR to rectus abdominus
59
Inguinal Canal
Aponeurosis of external oblique becomes the inguinal ligament both create inguinal canal parallel and superior to medial half of ligament contains spermatic cord and round lig of uterus
60
Inguinal Ligament
dense band inferior aspect of external oblique most fibers to pubic tubercle
61
Deep internal ring
entrance to inguinal canal contains round ligament of uterus & spermatic cord
62
Superficial external ring
exit for structures identified above from deep ring and illio-inguinal ligament
