Governs all sensory and motor actions

Intelligence learning analysis memory and language

7

What is the Pons?

Connection between the brain and the spinal cord

8

What is the medulla oblongata?

Center for controlling respiration, cardiac activity, vasomotor activity

9

What is the cerebellum?

Coordinates fine motor movement, Posture, equilibrium, and muscle tone.

10

Where is speech function controlled in the cerebrum?

The temporal lobe

Infection, Sepsis
Overdose
Uremia (Kidney Failure)

Trauma, tumor, toxins
insulin
Psychosis, poison
Strokes, seizure

24

what is tPA?

Tissue plasminogen activator

Designed to dissolve and break up clots.

Be mindful that tPA is not selective about clots, be mindful for patients with recent surgery and monitor for external and internal bleeding.

25
