Chapter 10 Flashcards
Place of union between two or more bones; also called a joint
articulation
Any body part attached to a main structure
appendage
Latticelike arrangement of bony plates occurring at the ends of long bones
cancellous
Ligaments that cross each other, forming an X within the notch between the femoral condyles
cruciate ligaments
Production and development of blood cells, normally in the bone marrow
hematopoiesis
contractile cells that provide movement of an organ or body part
fibers
Muscles whose action is under voluntary control
Skeletal muscle or voluntary muscle or striated muscles
Muscle found only in the heart, involuntary
Cardiac muscle
Muscles whose actions are involuntary, found in visceral organs, walls of arteries and respiratory passages, and urinary and reproductive ducts
Smooth muscle
In ________ muscle fibers arise directly from bone
fleshy attachments
In __________ the connective tissue converges at the end of the muscle to become continuous and indistinguishable from the periosteum
fibrous attachments
When the fibrous attachment spans a large area of a bone the attachment is called an
aponeurosis
When connective tissue fibers form a cord or strap it is called a
tendon
Flexible bands of fibrous tissue that are highly adapted for resisting strains and are one of the principal mechanical factors that hold bones close together in a synovial joint
ligament
Adduction
moves closer to the midline
Abduction
Moves away from the midline
Flexion
decreases the angle of a joint
Extension
increases the angle of a joint
Rotation
moves a bone around its own axis
pronation
turns the palm down
supination
turns the palm up
Inversion
moves the sole of the foot inward
Eversion
moves the sole of the foot outward
Dorsiflexion
elevates the foot
plantar flexion
lowers the foot (points the toes)
produce blood cells within bone marrow
hematopoiesis
cube shaped
consist of a core of spongy bone
enclosed in a thin surface layer of compact bone
short bone
include the bones that cannot be classified as short or long because of their complex shapes
irregular bones
provide a broad surface for muscular attachment or protection for internal organs
flat bones
found in the appendages (extremities) of the body, such as the legs, arms, and fingers
long bones
the shaft, or long, main portion of a bone. Consists of compact bone that forms a cylinder and surrounds a central canal called the medullary cavity.
diaphysis
cavity that contains fatty yellow marrow in adults and consists primarily of fat cells and a few scattered blood cells
medullary cavity or marrow cavity
A type of elastic connective tissue that provides a smooth surface for movement of joints
articular cartilage
surrounded by a layer of compact bone, within it is red bone marrow
spongy bone
A dense, white, fibrous membrane, that covers the remaining surface of the bone
periosteum
In growing bones, the inner layer that contains the bone forming cells
osteoblasts
Eight bones that enclose and protect the brain and the organs of hearing and equilibrium
cranium (skull)
incomplete bone formation
soft spot
bone that forms the anterior portion of the skull and the roof of the bony cavities that contain the eyeballs
frontal bone
______ bone that is situated on each side of the skull just behind the frontal bone
parietal bone
________ bone forms the back and base of the skull
occipital bone
Two ________ one on each side of the skull, form part of the lower cranium
