*Skeletal muscles work in pairs. When one contracts, the other relaxes. They are attached to bone by bands of tissue called tendons.

Fractures of the BoneA bone fracture is a medical condition in which a bone becomes cracked, splintered, or bisected as a result of physical trauma. A bone fracture can also occur as a result of certain medical conditions that weaken the bones, such as osteoporosis, certain types of cancer or osteogenesis imperfecta.
Osteoporosis (Gk. osteo- + pór (os) passage, pore)
osteomyelitis (pl. os·teo·my·elit·i·des; Gk. osteo + myelits)
osteopathy (Gk. Gk. osteon "bone" + -pathy)

osteoporosis (Gk. osteo- + pór (os) passage, pore)
pororsity
Word Family with “Osteo-”
osteoarthritis (pl. os.teo.arthr.i.des; Gk. osteo + arthritis)
e.g. porous
Closed fractures are those in which the skin is intact.
Open (compound) fractures involve wounds that communicate with the fracture and may expose bone to contamination. Open injuries carry an elevated risk of infection; they require antibiotic treatment and usually urgent surgical treatment (débridement).
Compression fracture is when the front portion of a vertebra in the spine collapses due to osteoporosis, a medical condition which causes bones to become brittle and susceptible to fracture (with or without trauma).
Other Types of Fracture are:
˙ Complete Fracture (a fracture in which bone fragments separate completely)
˙ Incomplete Fracture (a fracture in which the bone fragments are still partially joined)
˙ Linear Fracture (a fracture that is parallel to the bone's long axis)
˙ Transverse Fracture (a fracture that is at a right angle to the bone's long axis)
˙ Oblique Fracture (a fracture that is diagonal to a bone's long axis.
˙ Spiral Fracture (a fracture where at least one part of the bone has been twisted)
˙ Comminuted Fracture (A fracture causing many fragments)
˙ Impacted Fracture (A fracture caused when bone fragments are driven into each other)
