MSK 2 Flashcards
four principal types of bones are
long, short, flat and irregular
Bones that are longer than they are wide are called ___. They consist of a long shaft with two bulky ends or extremities.
Long bones
hold the skeleton together and support movement..
The first is by joint function, also referred to as range
of motion.
Joints
Full movement synovial capsule
hinge joint
Knee
Some movement cartilaginous
joint
Vertebrae
Immovable fibrous joint
Skull structures
Immovable joints (called __) include skull sutures, the
articulations between the teeth and the mandible, and the joint
found between the first pair of ribs and the sternum
synarthroses
joints allowing slight movement (called
amphiarthroses
Joints allowing full movement
(called
diarthroses
3 types of joint function
Synarthrosis
Amphiarthrosis
Diarthrosis
3 types of fibrous joints
Sutures
Fibrous
Syndesmosis
are nonmoving joints that connect bones of
the skull. These joints have serrated edges that lock together with fibers of connective tissue.
Sutures
The fibrous articulations between the teeth and the mandible or maxilla are called ___ and are also immovable
gomphoses
A is a joint in which a ligament connects two bones, allowing for a little movement (amphiarthroses). The distal joint between the tibia and
fibula is an example of a syndesmosis.

syndesmosis
are characterized by the presence of an
articular capsule between the two joined bones.
Synovial joints
move on just one axis. These joints allow for flexion and extension. include the elbow and finger joints.
Hinge joints
move against each other on a single plane.include the intervertebral joints and the bones of the wrists and
ankles
Gliding joints
allows for circular motion, flexion, and extension. The
wrist joint between the radius and the carpal bones is an example of a
condyloid joint.
condyloid joint
allows for flexion, extension, and other movements, but
no rotation. In the hand, the thumb’s saddle joint (between the first
metacarpal and the trapezium) lets the thumb cross over the palm, making
it opposable.
saddle joint
is a freely moving joint that can rotate on any
axis. The hip and shoulder joints are examples of ball and socket joints.
ball-and-socket joint
t provides rotation. At the top of the spine, the atlas and axis
form a pivot joint that allows for rotation of the head.
pivot joint
is the
tissue that connects,
separates and supports all
other types of tissues in the
body. Like all tissue types, it
consists of cells surrounded
by a compartment of fluid
called the ___
Connective tissue
extracellular matrix
A ___ is a tough band of
fibrous connective tissue that connects
muscle to bone and is capable of
withstanding tension.
tendon or sinew
Tendons are
similar to ligaments; both are made of
___.
collagen
connect one bone to
another, while ___ connect muscle
to bone.
Ligaments
tendons
is a form of
connective tissue in which the
ground substance is abundant
and of a firmly gelated
consistency that endows this
tissue with unusual rigidity and
resistance to compression
Cartilage
are bands of tough elastic
tissue around your joints. They connect
bone to bone, give your joints support,
and limit their movement.
Ligaments
