Exam 2 Flashcards
Major ways we dissipate heat
1) sweating
2) vasodilation/ increased skin blood flow
Thermoregulation occurs where:
Hypothalamus
Dehydration of ___% of body weight increases risk for heat illness
3%
Heat rash
Prickly heat. Redness/ rash. Treatment: allow skin to dry
Heat cramps
Result from loss of fluids. Rx: ice bath, stretch, massage
Heat exhaustion
Caused by inadequate replacement of fluids lost through sweating.
Collapse Profuse sweating Cool, clammy skin Rapid, weak pulse Electrolyte drink = watered down 3-4 times, so it can be absorbed faster into the GI tract
Heat stroke
Complete breakdown of thermoregulation Core temp > 106 degrees Disorientation/ loss of conciousness Flushed, hot skin No sweating, hot skin Rapid strong pulse First 45 mins are critical to cool the body
Ankle joint
Talocrural joint
Tibia, fibula, talus
ATF - Anterior talofibular ligament
Most commonly sprained ligament in ankle. Lateral ankle sprain. Plantar flexion and inversion
High ankle sprain
Anterior tib-fib ligament. Syndesmotic sprain MOI- dorsiflexion and twisting Severe Eversion Often need boot More serious
Jones fracture
Fracture to proximal 1/3 of 5th metatarsal
Deltoid ligament
Medial side of ankle
Medial retinaculum
Holds tendons in place.
Inversion sprains
80-85% of ankle sprains
Perineus brevis (peroneal tendons)
Insert at the base of the 5 metatarsal
Muscle origin
Fixed attachment
