PSIO 201 EXAMINATION QUESTIONS AND VERIFIED
ANSWERS
skeletal systems - contains bones, cartilage, ligaments, and other connective tissues that
attach bones to each other
Skeletal system functions - Support
Skeletal system functions - Protection
Skeletal system functions - Mineral storage
Skeletal system functions - Triglyceride storage
Skeletal system functions - Red and white blood cell formation (hemopoiesis)
Skeletal system functions - Leverage(assistance in movement)
Axial division - center (skull, thocacic cage, vertebral columnm, sternum)
Appendicular Vision - limbs and their attachments
Skull - Cranium and face
cranium bones - 8
face bones - 14
hyoid bones - 1
Auditory ossicles (ear bones) - 6
Vertebral column bones - 26
thorax - sternum and ribs
sternum bones - 1
Rib bones - 24
Axial skeleton - skull, hyoid, auditory ossicles, vertebral column and thorax
, Appendicular skeleton - Pectoral (shoulder) girdles, Upper limbs (extremities), Pelvic (hip)
girdle, Lower limbs (extremities)
Pectoral (shoulder) girdles - Clavicle (2), Scapula (2)
Upper limbs (extremities) - Humerus (2), Ulna (2), Radius (2), Carpals (16), Metacarpals
(10), Phalanges (28)
Pelvic (hip) girdle - Hip, pelvic or coxal bone (2)
Lower limbs (extremities) - Femur (2), Patella (2), Fibula (2), Tibia (2), Tarsals (14),
Metatarsals (10), Phalanges (28)
number of bones - 206 (can be more depending on the person)
Long bone - humerus
Short bone - wrist bone, trapezoid
Flat bone - sternum, rib
Irregular bone - vertebra, scapula
Sutural bone - kind of a flat bone (part of cranium)
they are between sutures of other
bones
Sesamoid bone - Patella
Sesamoid bone - form within pendants to have better ability to move and form b/c of
friction people who work more with their feet/hands have more sesamoid bone
these are not attached to other bones and are attached to tissue
Endosteum - line inside of bone
Medullary Cavity - Outside of bone, find yellow marrow in adults
Articular Cartilage - Covers end of bones to allow smooth gliding
Compact bone - more dense
Trabecular - little connectors, has holes that house red bone marrow
Periosteum - Connective tissue membrane covering external surface of bone
