Appendicular Skeleton

Pectoral Girdle

Pelvic Girdle

Appendages


APPENDICULAR SKELETON

MADE UP OF:

  • appendages/limbs

  • pectoral girdle

  • pelvic girdle

    Remember… 126 Bones!


PECTORAL GIRDLE

  • Consists of scapula and clavicle


SCAPULA (2) = shoulder blade

- glenoid cavity

articulates with humerus


Posterior view

Medial view

Anterior view


SCAPULA continued…

  • coracoid process(like a crow’s beak)  point of attachment for muscles


CLAVICLE (2) = collarbone

  • articulates with sternum and the scapula


Pause! Please… remember to refer to your Bone Markings Table if you need to; for example:

  • Glenoid = pit/socket/articular

    depression

  • Trochlea = structure resembling or acting like a pulley

  • Tuberosity = large, rounded projection


UPPER LIMBS

  • HUMERUS (2)

  • Humerus articulates

    with glenoid cavity

    of scapula

  • Distal trochlea

    articulates with

    the ulna


RADIUS (2)= Lateral bone (thumb side)

  • The head of the radius articulates with the humerus

  • The radius forms most of joint with wrist bones

  • radial tuberosity= projection where the tendon of the biceps muscle attaches


ULNA (2)

  • trochlear notchof ulna articulates with trochlea of humerus


HAND

Made up of 27 Bones Total

CARPALS (16) = wrist 

8 bones each hand (2 rows of 4)

  • METACARPALS (10) = palm

    5 bones each hand

  • PHALANGES (28) total = fingers

    14 bones each hand


Some important features of the…PELVIC GIRDLE!

  • Helps protect/support the abdominopelvic organs

  • PELVIS includes coxal bones (hip bones) of appendicular skeleton & sacrum and coccyx of axial skeleton


HIP/PELVIC/COXAL BONE (2)

  • Each coxal bone is formed by the fusion of 3 bones

  • The coxal bones join anteriorly at the pubic symphysis which is cartilage


COXAL bone cont.

  • acetabulum= deep depression that articulates with the head of the femur


Side note: Is it a…Male or Female Skeleton?

FEMALE PELVIS

  • Female pubic arch is more rounded

  • Angle of the pubic arch is greater (wider pelvic inlet than male)

  • Female pelvis lighter


FEMUR (2)

= thighbone longest & heaviest bone in the body

  • headof femur articulates with the acetabulum of coxal bone

  • greater trochanterof femur is a site for muscle attachment


FIBULA (2)

= Thinner lateral lower leg bone

  • Head of fibula articulates with the tibia

    but fibula does NOT articulate with the femur


TIBIA (2)

= Large medial lower leg bone

  • Inferior surface of tibia articulates with proximal bone of the ankle

  • tibialtuberosity= roughened projection on the anterior surface where the patellar ligament attaches


PATELLA (2)

= sesamoid kneecap bone

  • Posterior surface articulates with the rounded projections of the femur


TARSALS (14)

  • 7 bones each ankle

    talus:most superior tarsal bone (articulates with tibia and fibula)

    calcaneus:largest/ strongest tarsal = heel bone


METATARSALS (10)

  • 5 bones long bones each foot

  • form the distal portion of the foot where foot arch is normally located


PHALANGES (28) = toe bones

  • 14 bones each foot

  • The hallux(big toe) has

    2 phalanges

  • Other 4 toes have 3 phalanges
