a pneumothroax
referred pain
a type of visceral pain that travels along the same nerve pathways as somatic pain
the beginning of the acute inflammatory phase of healing involves
acting to stop blood loss from the wound
normal pulse rates adult and child
adult: 60-100 bpm child: 120-140 bpm
strain
amount of deformation with respect to the original dimensions of the structure; injury to the musculotendinous unit
injury is caused by:
an abnormal force (push or pull on the body)
what is the major vessel of the trunk
aorta
somatic pain
arises from skin, muscles, and joints - deep or superficial
application of cold
as the temperature of peripheral nerves decreases, pain perception decreases - cold, burning/aching, numbing (analgesia)
Bilateral vs Contralateral vs Ipsilateral
bilateral: both sides contralateral: opposite side Ipsilateral: same side
joint
bone to bone
