on blood platelets and clotting, aspirin is often prescribed prophylactically for those at risk of stroke or heart attack. Salicylates are useful, relatively safe drugs, but normal doses can cause

rest of the body. Skeletal dysplasia is sometimes called
dwarfism. Others called skeletal abnormalities are short arms and trunk, bowlegs, waddling gait
macrocephaly, craniosynostosis, wormian bones, polydactyly, chest anomalies, abnormal fingernails and toenails, cataracts, myopia, cleft palate,
deafness, hydrocephaly, porencephaly, hydraencephaly, agenesis of the corpus callosum, atrial septal defect, patent ductus arteriosus,

body shape, and help the body with everyday movements. They are
voluntary muscles. They can contract quickly and powerfully, but tire quickly easily                                               and
have to rest between  workouts.                                          

skeletal muscle fiber --  see skeletal muscle.

skeleton --
a matrix made of bones which forms the shape and form for the body as well as supporting, protecting, allowing bodily movement, producing                                        blood, and

bone marrow. An average of 2.6 million red blood cells are produced each second by the bone marrow to replace those worn out and destroyed by the

social symptoms -- one of the three major characteristics of autism (along with communication difficulties and repetitive behaviors): tremendous difficulty learning to engage in the give-
and-take of everyday human interaction. Even in the first few months of life, many children with autism avoid eye contact and do not interact. They seem indifferent to other people, and often
seem to prefer being alone. They may resist attention or passively accept hugs and cuddling. Parents who look forward to the joys of cuddling, teaching, and playing with their child may feel
crushed by this lack of the expected and typical attachment behavior. Children with
autism spectrum disorder (ASD) are slower in learning to interpret what others are thinking or feeling.
Subtle social cues, whether a smile, wink, or a grimace, may have little meaning. Although not universal, it is common for people with ASD to have difficulty regulating their emotions. This can
take the form of immature behavior such as crying in class or verbal outbursts that seem inappropriate to those around them. The individual with ASD might also be disruptive and physically
aggressive at times, making social relationships still more difficult. They have a tendency to "lose control" particularly when they're in a strange or overwhelming environment, or when angry
or frustrated. They may at times break things, attack others, or hurt themselves. In their frustration, some bang their heads, pull their hair, or bite their arms. A child with autism may also have
