Skeletal System (lab manual) Flashcards
What are the (4) parts of the skeletal system?
Cartilage, bone, ligaments, and joints
206 bones
What % do bones account for of our body weight?
18%
What are the two divisions of the skeletal system?
Axial and Appendicular skeleton
axial = cranial and spinal
appendicular = limbs and everything else
What are bone markings?
Surface features present on bones such as projections or depressions
What kind of projections (bone markings) are present for bone connections?
Process
What kind of projections (bone markings) are present for attaching muscles, tendons, or ligaments?
Trochanter, crest, spine, tubercle, tuberosity
What kind of projections (bone markings) are present for joints?
Head, neck, facet, condyle, trochlea
What are the bone markings that are openings?
Foramen, fissure, canal
What are the bone markings that are depressions?
Fossa, sulcus
What makes up the axial skeleton?
Head = skull, jaw
Neck and Trunk = vertebral column, sternum, ribs
80 bones
What makes up the appendicular skeleton?
upper and lower limbs, pelvic girdle (lower limb girdle), pectoral girdle (upper limb girdle)
126 bones
Bones of the upper limb?
Arm bone = humerus
Forearm bones = radius, ulna
Hand bones = 8 carpals, 5 metacarpals
Digital bones = phalanges, 3 per finger except 2 per thumb
Bones of the lower limb?
Thigh bone = femur
Knee cap = patella
Lower leg bone = tibia, fibula
Foot bones = 7 tarsals, 5 metatarsals
Digital bones = phalanges, 3 per finger except 2 per big toe
