Skin and Bones Flashcards
(28 cards)
parts of the bone
compact, spongy, bone marrow
compact bone
dense, hard layer
spongy bone
found inside the ends of long bones
bone marrow
soft tissue inside bones
red marrow
produces red and white blood cells and platelets
yellow marrow
stores fat
diaphysis
long, central shaft of a bone
epiphysis
the rounded edge of the bone
cartilage
smooth tissues covering the ends of bones at joints
role of bone marrow
bone marrow is a soft, spongy tissue found inside bones, with2 primary types
joints
Areas where two or more bones meet, allowing movement and providing stability.
types include hinge, ball-and-socket, pivot, and fixed joints.
ball and socket
a ball shpaed end of one bone fits into a cup like socket of another
allows the widest range of motion
eg shoulder, hip
fixed
(immovable)
bones that are fused or tightly joined by firbrous tissue
no movement
eg skull
pivot joint
a bone rotates around another bone
allows rotation
eg neck
hinge joint
bones fit together like a door hinge
movement in one direction
eg elbow and knee
role of musculoskeletal system
6
support, movement, protection, blood cell production, mineral storage, flexibility
skeletal muscle
stripped muscle fibres found attaching bones by tendons
smooth muscle
involuntary, non-striated muscle fibres, found in walls of internal organs
eg stomach, intestines, blood vessels
cardiac muscle
involuntary, striated muscle fibres
found only in the heart
contracts to pump blood throughout the body controllong heartbeats
types of muscle attachments
tendons
strong flexible bands of tissue that connect the muscle to bone
Electromagnetic spectrum
The full range of electromagnetic radiation, from the longest wavelengths to the shortest
Electromagnetic spectrum made up of
7
radio waves, microwaves, infrared, visible light, UV, X-rays, Gamma rays
x-rays in diagnosis
used to view bones, tumors, lung conditions
x-rays in treatment
radio therapy
