skeletal system Flashcards
forms the framework of the body, protects vital organs, and works with the muscular system to
produce movement at the joints. The human adult skeleton is composed of 206 bones, which are organized for
study into two divisions.
skeleton
The human adult skeleton is composed of ___ bones, which are organized for
study into two divisions.
206
forms the
central structure of the body,
providing support and
protection for vital organs
axial skeleton
axial- consists of ____ bones which
includes the skull, hyoid bone,
auditory ossicles, thorax, and
vertebrae
80
appendicular skeleton consists of ____ bones and
includes the limbs and
structures that support
movement namely the
pectoral girdle, upper limb,
lower limb, and pelvic girdle.
126
How many bones make up the adult
vertebral column?
26
The sternum is part of which region of
the axial skeleton?
thorax
What joint is formed when the mandibular fossa
articulates with the condylar process?
Temporomandibular
Which is the longest and strongest bone in the
human body?
Femur
an inflammation of
bone caused by pus-forming bacteria
that enter through a wound or are
carried by the blood
Osteomyelitis
may spread to bone,
especially the long bones of the arms
and legs and the bones of the wrist and
ankle.
tuberculosis
Tuberculosis of the spine is
Pott’s
disease
break in a bone, usually caused by trauma.
FRACTURE
most commonly occurs in a bone’s
growing region, especially around the
knee.
Osteogenic sarcoma (osteosarcoma)
usually appears in
midlife. As the name implies, this tumor
arises in cartilage.
Chondrosarcoma
a loss of bone mass that results
in bone weakening
Osteoporosis
refers to a lower-than-average bone
density, which is not considered to be abnormal
Osteopenia
a softening of bone tissue
because of diminished calcium salt formation
Osteomalacia
(osteitis deformans) is a
disorder of aging in which bones become
overgrown and thicker but deformed.
Paget’s disease
a term broadly used to mean any
inflammation of a joint.
Arthritis
The most common form of arthritis is _____. This involves a gradual
degeneration of articular (joint) cartilage
osteoarthritis (OA) or degenerative joint
disease (DJD).
a disease of the
spine that appears mainly in males. Joint
cartilage is destroyed; eventually, the disks
between the vertebrae calcify and there is
ankylosis (fusion) of the bones
Ankylosing spondylitis
a forward sliding of a
vertebra over the vertebra below.
The condition follows spondylolysis,
degeneration of the joint structures that
normally stabilize the vertebrae.
Spondylolisthesis
