25

26
What are additional foramina and what are some.
holes or openings ex; - rotundum - ovale - spinosum - lacerum (located on sphenoidal bone) - jugular foramen
27
parts of the orbit:
- supra and infraorbital fissues (aso called superior and inferior orbital fissures) - optic foramen/canal - hard palate: palatine bone and maxilla
28
part of nasal cavity
- nasal bones - ethmoid/al bone - vomer - inferior nasal concha - maxilla (vomer & ethmoid bone = nasal septum)
29
find the hyoid bone
google it
30
parts of mandible
- mandibular condyle/condylar process - coronoid process - mental foramen - mandibular foramen - ramus - body of the mandible
31
parts of paranasal sinuses:
- maxillary - sphenoid - ethmoid - frontal
32
parts of vertebral column:
- cervical (7) - thoracic (12) - lumbar (5) - sacral (fused from 5) - coccyx (fused from 4)
33
C1 =
atlast
34
C2 =
Axis
35
for C1 and C2, identify both vertebrae and dens of ais
C1 (Atlas): The atlas is the first cervical vertebra. It lacks a body and spinous process. Instead, it has large lateral masses that support the skull. The atlas has an anterior and posterior arch and a large vertebral foramen. It articulates with the occipital condyles of the skull, allowing for the nodding "yes" motion (flexion and extension). C2 (Axis): The axis is the second cervical vertebra. It has a unique feature called the dens (also called the odontoid process), which is a peg-like projection extending upward from the body of the axis. The dens fits into the anterior arch of the atlas and is held in place by the transverse ligament. This pivot joint between the dens of C2 and C1 allows for the "no" motion (rotation) of the head. Dens of Axis (C2): The dens is critical for head rotation. It acts as a pivot point for the atlas and the skull to rotate around the axis. In summary, the atlas (C1) supports the skull and permits nodding movements, while the axis (C2), with its dens, allows for rotational movements.
36
What are the parts of a general vertebra model: & Identify these parts ONLY on thoracic vertabra (APR video)
- body/centrum - vertebral foramen - spinous process - transverse process - pedicle (between the body and transverse process) - lamina (between the transverse and spinous process) - superior and inferior articulating processes and facets
37
Differentiate between cervical/thoracic and lumbar vertebrae (body and shape of vertebral foramen; cervical: rat, thoracic: giraffe, lumbar: moose)
ill do this later...
38
parts of sacrum
sacral foramina, medial (or median) sacral crest, sacral hiatusm and identify the coccyx
39
parts of sternum:
3 MAJOR PARTS: - Manubrium - Gladiolus (Body or Centrum) - Xiphoid Process
40
parts of ribs and difference between false and true ribs:
*note its in pairs* 12 total - 7 true ribs - 5 false ribs - 2 floating ribs (floating is apart of the false) True Ribs: Costal cartilage articulates anteriorly directly with the sternum - simply put; True ribs direclty connect to sternum False Ribs: Do not articulate directly with the sternum - simply put false ribs connect to sternum via cartilage
41
how many bones are in the appendicular skeleton
126
42
can you identify where the pectoral girdle is and the parts?
parts: - scapula - clavicle
43
can you identify where the clavicle is
test yourself
44
can you identify where the scapula is and the parts?
parts: - subscapular fossa - supraspinous fossa - infraspinous fossa - glenoid cavity (glenoid fossa) - acromion - coracoid - spine of the scapula
45
can you identify where the humerus is and the parts of it:
parts: - greater tubercle - lesser tubercle - trochlea (can be seen in anterior and posterior) - capitulum (only anterior) - head of the humerus - olecranon fossa
46
can you identify where the radius is and parts of it
- head of radius
47
can you identify where the ulna is and parts of it
trochlear notch
48
Distinguish - Carpal bones - metacarpal bones - phalanges how many in each
Carpal bones (8) Metacarpal bones (5) phalanges (14)
49
can you identify where the carpal bones are and parts of it
- hanmate (has a hook) - capitate (largest) - trapezoid - trapezium (joint with thumb) - triquetrum - pisiform (articules only with the triquetrum - lunate - scaphoid (most likely to break in children) - pisiform visible only in anterior view
50
can you identify where the pelvic girdle is and parts of it
- coxal bones (os coxae)
51
Difference between male and female pelvis
Main thing i remembered from class: Male: Narrower, V-Shaped (below 80-90 degrees) Female, Wider, U-Shaped (around 80-90 degrees)
52
identify where the coxal bone is and it's parts:
main 3: - ilium - ischium - pubis additional parts: - obturator foramen - pubic symphysis - anterior superior iliac spine - acetabulum (acetabular fossa) - iliac fossa (body of the ilium)
53
identify where the femur is and parts of the femur
- head of femur - fovea capitis - greater trochanter - lessen trochanter - medial epicondyle - lateral epicondyle - medial condyle - lateral condyle - patellar surface
54
# i identify where the patella is
go look
55
identify where the tibia is and parts of it
- tibial tuberosity - medial malleolus - medial and lateral condyle(s) - medial malleolus - inner/internal ankle
56
identify where the fibula is
says something about lateral malleolus = outer/external ankle
57
distinguish the difference between: - tarsal bones - metatarsal bones - phalanges (how many in each)
in ONE foot: - tarsal bones (7) - metatarsal bones (5) - phalanes ; proimal-middle-distal ; (14)
58
identify parts of tarsal bones
- talus - calcaneus - cuboid - navicular - medial-intermediate-lateral cuneiform
