Skeletal System Worksheet

Drag each label into the proper position in order to identify whether it refers to the axial or appendicular skeleton

axial: - skull - hyoid - sacrum - sternum - mandible - 80 bones in the adult - rib appendicular: - clavicle - fibula - 126 bones in the adult

Place the anatomical features in the appropriate highlighted category below based on their location in the axial or appendicular skeleton

axial: - spinous process - mastoid process - jugular process - mandibular fossa - foramen magnum appendicular: - trochlea - olecranon - tibial tuberosity - radial tuberosity - greater trochanter

Drag each label into the proper position to identify whether the indicated structure borders the orbit, cranial cavity, or both

cranium: - occipital - parietal - temporal both: - sphenoid - ethmoid - frontal orbit: - lacrimal - zygomatic - maxilla

Drag each label into the proper position to identify whether the indicated structure is located on the femur, humerus, or both

humerus: - lesser tubercle - olecranon fossa - trochlea - capitulum both: - lateral epicondyle - neck - head - medial epicondyle femur: - greater trochanter - intercondylar fossa

Place the bones of the upper appendicular skeleton in order as they would be encountered in anatomical position as you moved distally

proximal to distal: - clavicle - scapula - humerus - ulna - lunate - trapezoid - metacarpal II - proximal phalanx II - middle phalanx II - distal phalanx II

Drag each label into the proper position to identify whether the given bone is paired (right and left) or unpaired (singular)

unpaired: - hyoid - ethmoid - occipital - vomer - mandible - sacrum paired: - patella - humerus - maxilla - nasal - parietal - clavicle

Match each type of bone marking with its definition

- A narrow ridge: Crest - An extended region superior to a condyle: Epicondyle - A slightly raised, elongated ridge: Line - A bony outgrowth or protruding part: Protuberance - A small rounded process: Tubercle

List the sutures surrounding the parietal bones. Check all that apply

- Sagittal - Squamous - Coronal - Lambdoid - Frontonasal - Occipitomastoid

Complete each sentence by dragging the proper word or phrase into the appropriate position

- The analogous structure of the upper extremity to the femur is the HUMERUS - As the larger of the two bones at the wrist, the RADIUS is the equivalent of the tibia in the lower extremity - As a critical site of muscular attachments for the rotational control of the humerus, the SCAPULA is developmentally similar to the os coxal bones of the lower extremity - Developmentally, the first digit is laterally positioned in the upper extremity and MEDIALLY located in the lower extremity

Match each type of rib with its definition

- These ribs do not have independent cartilaginous connections to the sternum: False ribs - These ribs do not attach to the sternum: Floating ribs - These ribs have independent costal cartilages that attach to the sternum: True ribs

Label the bones of the pelvis

left side top to bottom: - ilium - coccyx - ischium right side top to bottom: - intervertebral disc - lumbar vertebra - sacrum - pubis

Label the structures of the bone

left side top to bottom: - proximal epiphysis - shaft (diaphysis) - distal epiphysis middle top to bottom: - humerus - medial epicondyle right side top to bottom: - head - deltoid tuberosity - lateral epicondyle

Drag each label into the proper position to identify whether the indicated structure is located in the forearm, lower leg, or both

lower leg: - malleoli - fibula - medial condyle - anterior crest both: - interosseous membrane forearm: - olecranon process - ulna - radial tuberosity - trochlear notch - coronoid process

Drag each label into the proper position to identify whether the term or phrase is referring to a female or male pelvic characteristic

male: - pubic arch less than 90 degrees - heart-shaped pelvic inlet - narrower false pelvis - round obturator foramen female: - shallow lesser pelvic - coccyx moveable and titled posteriorally - anterior pelvic tilt - shorter sacrum - wider sacrum - wide greater sciatic notch - anteriorly facing acetabulum
