THE NERVOUS SYSTEM
|
RECEIVES AND TRANSMITS INFORMATION
|
|
|
CENTRAL NERVOUS SYSTEM
|
BRAIN AND SPINAL CORD
|
|
|
BRAIN
|
SPLIT INTO RIGHT AND LEFT HEMISPHERES; EXHIBITS CONTRA LATERAL CONTROL; 3 MAJOR PARTS = HINDBRAIN, MIDBRAIN AND FOREBRAIN
|
|
|
CONTRA LATERAL CONTROL
|
EACH HEMISPHERE OF THE BRAIN CONTROLS OPPOSITE SIDE OF BODY;
EX: WHEN YOU'RE LEFT HAND MOVES, THE RIGHT HEMISPHERE IS CONTROLLING THAT MOVEMENT AND VICE VERSA |
|
|
LATERALIZATION
|
LEFT AND RIGHT HEMISPHERES OF THE BRAIN HAVE DIFFERENT FUNCTIONS
|
|
|
HINDBRAIN
|
TOP PART OF THE SPINAL CORD; INCLUDES MEDULLA, PONS AND CEREBELLUM
|
|
|
MEDULLA
|
BASIC BIOLOGICAL FUNCTIONS LIKE BREATHING, SWALLOWING, AND BALANCE; primarily responsible for breathing, heart rate, blood pressure, and coughing.
|
|
|
PONS
|
FACIAL EXPRESSIONS, SLEEP AND DREAMING; act as a major pathway for motor and sensory information between the body and higher level brain functioning.
|
|
|
MIDBRAIN
|
COORDINATES BASIC MOVEMENTS WITH SENSORY INFORMATION; a portion of the brain located just above the medulla and pons and contains basic vision and hearing functions; it also is the input center for muscle movement.
|
|
|
Forebrain
|
Large in Humans; includes the CEREBRAL CORTEX and SUB CORTICAL STRUCTURES: thalamus, hypothalamus, basal ganglia
|
|
|
BASAL GANGLIA
|
REGULATES MUSCLE CONTRACTIONS AND MOVEMENTS; An area of the forebrain that is important to smooth muscle movement and actions. This area works in conjunction with the midbrain to help us avoid moving in choppy, fragmented ways.
|
|
|
THALUMUS
|
a structure deep within the brain stem that receives sensory information from the nervous system and passes the information to the cerebral cortex and other parts of the brain. It acts as a director of information related to bodily functions such as seeing, sleeping, hearing, waking, tasting, and touching; INCORPORATES AND RELAYS SENSORY INFO TO THE CORTEX
|
|
|
HYPOTHALAMUS
|
CONTROLS MOTIVATED BEHAVIOR LIKE EATING, DRINKING, SEX; SITS BELOW THE THALUMUS ; helps govern the endocrine system (glands that produce hormones) using the pituitary gland, and is also involved in feeling emotions and perceiving things are rewarding (for example, being in love is perceived as a good and rewarding feeling/emotion and something worth trying to obtain more of)
|
|
|
HIPPOCAMPUS
|
HELPS PROCESS AND RECEIVE LONG TERM AND SPATIAL MEMORY
|
|
|
AMYGDALA
|
EMOTION; EVALUATION OF STIMULI; actually 2 areas of the brain (not one) containing lots of neurons that influence anger, aggression, fear, and rage. Although there are other parts of the brain that influence these emotions, the ______ may have the most influence. Early studies demonstrated that damaging these areas can turn very aggressive animals into docile, even fearful creatures
|
|
|
CEREBRAL CORTEX
|
The thin outer layer of the brain's (approximately 2 mm) cerebral hemispheres that acts as the main control center and information processing center; is not required for performing many simple actions, but is crucial for creating new episodic memories, the fancier associations, and many new movement programs; made up of two different sub-components: the motor cortex and the sensory cortex; CONSISTS OF FOUR LOBES
|
|
|
CORPUS CALLOSUM
|
NERVE TRACT BENEATH CORTEX THAT CONNECTS THE TWO HEMISPHERES AND ALLOWS THEM TO COMMUNICATE
|
|
|
OCCIPITAL LOBES
|
PROCESSES VISION
|
|
|
TEMPORAL LOBE
|
PROCESSES SOUND
|
|
|
PARIETAL LOBE
|
The area in the brain which plays a major part in touch, pressure and temperature; would inform you the temperature of a hard boiled egg and would allow you to pick up that egg with just enough pressure to hold it and not crush it.
|
|
|
FRONTAL LOBE
|
SPEECH, LEARNING, THINKING, DECISION MAKING, AND ABSTRACT THOUGHT
|
|
|
PERIPHERAL NERVOUS SYSTEM
|
INCLUDES ALL NERVES THAT SPREAD THROUGH THE BODY FROM THE BRAIN AND SPINAL CORD
|
|
|
SOMATIC DIVISION
|
CONTROLS VOLUNTARY MUSCLE MOVEMENTS AND SENSE ORGANS
|
|
|
AUTONOMIC DIVISION
|
CONTROLS INVOLUNTARY ACTIONS AND THE INTERNAL ORGANS
|
