Excluding moderate and severe tbi, what may cause concussion symptoms?

The concussion is an immediate and transient loss of neuronal function secondary to trauma. (Neuronal Function = LOC, memory or motor skills).

The impact shakes the brain inside the skull, a wave through brain tissue causes discharge of damaging chemicals; nerve cells can shear, microscopic damage can affect the anatomy and function of brain cells.

It is a mild traumatic brain injury caused by a bump, jolt, or blow to the head. 

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
