Appendicular skeleton1
APPENDICULAR SKELETON

MADE UP OF:

  • appendages/limbs

  • pectoral girdle

  • pelvic girdle

    Remember… 126 Bones!


Pectoral girdle
PECTORAL GIRDLE

  • Consists of scapula and clavicle


Scapula 2 shoulder blade
SCAPULA (2) = shoulder blade

- glenoid cavity

articulates with humerus


Appendicular skeleton

Posterior view

Medial view

Anterior view


Scapula continued
SCAPULA continued…

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


Clavicle 2 collarbone
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
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
UPPER LIMBS Table if you need to; for example:

  • HUMERUS (2)

  • Humerus articulates

    with glenoid cavity

    of scapula

  • Distal trochlea

    articulates with

    the ulna


Radius 2 lateral bone thumb side
RADIUS Table if you need to; for example:(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
ULNA Table if you need to; for example:(2)

  • trochlear notchof ulna articulates with trochlea of humerus


Appendicular skeleton
HAND Table if you need to; for example:

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
Some important features of the… Table if you need to; for example: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
HIP/PELVIC/COXAL BONE Table if you need to; for example:(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
COXAL bone cont. Table if you need to; for example:

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


Side note is it a male or female skeleton
Side note: Table if you need to; for example: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
FEMUR Table if you need to; for example:(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
FIBULA Table if you need to; for example:(2)

= Thinner lateral lower leg bone

  • Head of fibula articulates with the tibia

    but fibula does NOT articulate with the femur


Tibia 2
TIBIA Table if you need to; for example:(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
PATELLA Table if you need to; for example:(2)

= sesamoid kneecap bone

  • Posterior surface articulates with the rounded projections of the femur


Tarsals 14
TARSALS Table if you need to; for example:(14)

  • 7 bones each ankle

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

    calcaneus:largest/ strongest tarsal = heel bone


Metatarsals 10
METATARSALS (10) Table if you need to; for example:

  • 5 bones long bones each foot

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


Phalanges 28 toe bones
PHALANGES Table if you need to; for example:(28) = toe bones

  • 14 bones each foot

  • The hallux(big toe) has

    2 phalanges

  • Other 4 toes have 3 phalanges
