Which brain lobe plays a role in proprioception?
Parietal lobe
Which lobe contributes to hearing?
Temporal lobe
Which brain lobe helps with sight?
Occipital lobe
Which lobe contributes to emotions and personality?
Frontal lobe
What are the parts of the Central Nervous System, and what are their functions?
The brain and the spinal cord. The brain is the central command center organ and it controls “complex” decisions. The spinal cord helps with simple decisions and information transmission
What are the parts of the Peripheral Nervous System?
Somatic and Autonomic
sensory information & voluntary movement.
Somatic
Sympathetic - increases support increased physical activity.
Parasympathetic - increases support decreases physical activity.
Autonomic
Base unit that has very simple function – “decide” whether to transmit signal or not
Nerve
Collection of cell bodies and dendrites
Ganglia
What do Glial cells do?
Support and assist neurons
About how many neurons does a human have?
About 100 billion
System of bones which are alive
