General paralysis Severe damage to spinal cord Loss feeling from injury down Quadriplegia—lose control of both arms and legs
Paraplegia Lose control of just the legs Repair Impossible naturally No cell division of neurons Trying artificial division Uses stem cells
About 35 billion neurons About 3 pounds Cerebrospinal fluid (CSF) Brain floats in this Makes brain light Transports nutrients, neurotransmitters, and wastes Lumbar puncture—useful in determining CNS disease Replaced every 8 hours
Largest part of the brain Conscious Thought Intelligence Gray matter—superficial layer White matter—deep layer Contains axons Gyri—grooves that increase the surface area Left and Right Lobes Control opposite sides of the body
Parietal Lobe Primary motor cortex Directs voluntary movements Primary sensory cortex Receives somatic sensory information Ex: Touch, pressure, pain, temperature
Occipital Lobe Visual cortex All visual information
Frontal Lobe Gustatory cortex Taste sensations
Temporal Lobe Auditory cortex—hearing Olfactory cortex—smell
