|
|
Term

|
Definition
| thalamus, hypothalamus, ponds, and medulla oblongata |
|
|
Term

|
|
Term

|
Definition
| To coordinate body movements and posture and help maintain body equilibrium |
|
|
Term
| What is the frontal lobe responsible for |
|
Definition

|
|
Term
| What is the cause of Parkinson's disease |
|
Definition
| Degeneration of neuron's within the basal ganglia that produce dopamine |
|
|
Term
| When excitatory fibers are stimulated by various external stimuli [toys, bright light, or danger] |
|
Definition
| The degree of alertness increases, preparing the body for a simulation that requires action |
|
|
Term
| What are excitatory fibers usually referred as |
|
Definition
| Reticular activating system (RAS) |
|
|
Term
| It have it's very fibers of the right to live formation decreases brain activity this decrease normally occurs during periods of rest or sleep what does the reticular formation help regulate |
|
Definition
| The degree of alertness or wakefulness of the nervous system |
|
|
Term
| What do stimulants such as amphetamines and caffeine do |
|
Definition
| Increase the activity of the reticular formation and are usually used for abuse to stimulate the central nervous system to maintain wakefulness |
|
|
Term
| Located at the top of the brainstem what does thalamus must do |
|
Definition
| Receives and evaluates almost all of the sensory nerve impulses from Periphal sensory receptors before passing the information to the cerebral cortex |
|
|
Term
| The cerebral cortex contains the cell bodies of neurons (Gray matter) that |
|
Definition
| Perceive and are actively involved with all conscious activities of the mind and intellect |
|
|
Term

|
Definition
| Regulates the function of many other endocrine glands |

|
Definition

|
|
Term
| Nerve axons traveling from the brain to the peripheral organs and skeletal muscle (afferent neutrons) |
|
Definition
| Carey motors impulses that direct organ activity and muscle movement |
|
|
Term
| The limbic system is involved with emotional and behavioral responses of the body associated with |
|
Definition
| Reward and punishment, sexual behavior, anger or rage, fear, and anxiety; therefore the limbic system is important to mental health |
