Ribs

12 ribs connected to vertebrae. The ribs, false ribs, floating ribs

Thoracic vertebrae

12 thoracic vertebrae

Ilium

Largest part of the vocal bone

Fibula

Lateral (away from midline) to the tibia and stabilizes ankle

Ischium

Most inferior part of the coxal

Function of vertebrae

Protect spinal cord, support rib cage, attaches to pelvis

Bones of the lower limb

Femur, patella, tibia, fibula, tarsals, metatarsals, and phalanges

Fontanelles

Fibrous membranes connecting the cranial bones allowing the brain to grow. Converts to bone within 24 months after born

Sternum

Flat, blade shaped bone composted of three bones: manubrium, body, xiphoid process

Patella

Triangular bone that protects the knee joint

Phalanges

Toes

Iliac crest

Top of the ilium

Forearm

Two bones: radius and ulna

Hip bones Protect several organs

Reproductive system, urinary bladderX and part of the large intestine

2 parts of body

Axial (skull, vertebral column, and rib cage) and appendicular (bones of arms and legs, shoulders, and pelvis)

Female pelvis

Wider pelvis, broad hips, pelvic cavity is shallow, bones are lighter, and pubic arch is wider

Maxilla

2 bones that form the upper jaw

Zygomatic bones

2 cheek bones

How many bones in the adult human body

206; divided into 2 parts

Tarsal bones

Ankle, heel, supports weight of body

Pubis

Anterior part of coxal bone

False ribs

Attach to the sternum by cartilage

Pectoral girdle

Bones allow upper limbs to have exceptionally free movement. Composed of 4 bones (2 clavicle- collarbones and 2 scapulae- shoulder blade)

Bones of cranium (skull)

Bones attached to immovable joints called sutures: 1 frontal, 2 parietal, 1 occipital, 2 temporal, 1 sphenoid, 1 ethmoind

Hand

Carpal (wrist) metacarpals (palm) phalanges (fingers)

Names of vertebrae

Cervical, thoracic, lumbar, sacrum, coccyx

Axial skeleton

Divided into three parts (skull, vertebral column, and rib cage)

Floating ribs

Do not attach to the sternum

Upper arm

Formed by a single bone: humerus

Rib cage

Forms a cage to protect major organs (24 total 12 on each side)

Nasal bone

Forms bridge of the noise

Bones of the pelvic girdle

Hip bones made of 2 coxal (hip bones), sacrum, coccyx

Bones of upper limb

Humerus, radius, ulna, carpals, metacarpals, phalanges

Coxal bone is made of

Ilium, iliac crest, ischium, pubis, and pubic symphasis

Xiphoid process

Inferior and smallest portion of the sternum attachment site of diaphragm

Mandible

Lower jaw. Only moveable bone of the skull containing tooth sockets for 16 teeth

Male pelvis

Not as wide, pelvic cavity is funnel shaped, heavier bones, pubic arch is wider

Appendicular system

Pectoral girdle, limbs, pelvic girdle

True ribs

Ribs that connect directly to the sternum

Vertebrae

Separated by intervertebral discs. Spine has 4 normal curvatures

Tibia

Shin bone, medial (towards the fibula), and thicker (bears wear of femur)

Metatarsals

Sole or instep

Femur

Thigh bone, strongest and longest bone of body

The skull

Two sets of bones: cranium and facial bones. Only the mandible is attached by a freely moveable joint. Protects brain

Pubic symphasis

Where the two pubic bones meet
