Section 5: Axial & Appendicular Skeleton - Anatomy

Axial skeleton bones:

Skull, vertebral column, ribs, sternum, hyoid, and auditory ossicles.

Only movable skull bone

Mandible

Fossa

Shallow depression or hollow in a bone.

Appendicular skeleton bones

Upper and lower limbs, pectoral girdle, and pelvic girdle

Vomer:

Thin facial bone forming the lower and posterior portion of the nasal septum

Parts of axial skeleton

Skull, vertebral column, thoracic cage, hyoid, and auditory ossicles.

Male vs. female skeletal differences relate to:

Adaptation for childbirth, especially the female pelvis.

Opening or hole in a bone:

Foramen

Part of the elbow joint:

Trochlear notch of the ulna (articulates with the humerus).

Genu varum

Bowlegs

Parts of scapula:

Spine, acromion, coracoid process, glenoid cavity, supraspinous and infraspinous fossae, and subscapular fossa.

Tendons vs. ligaments

Tendons connect muscle to bone; ligaments connect bone to bone.

Cranial bones

Frontal, parietal (2), temporal (2), occipital, sphenoid, ethmoid.

Common elderly hip fracture location:

Femoral neck.

Greater and lesser trochanters found on

Femur
