Central Nervous System consists of:
|
The brain and spinal cord
|
|
|
The brain and spinal cord make up the:
|
Central Nervous System
|
|
|
Cerebral Cortex
|
-more developed in humans than in any other animal
-what we see when we imagine a brain -involved in a variety of higher cognitive, emotional, sensory, and motor functions |
|
|
Cerebrum
|
1. the anterior and largest part of the brain, consisting of two halves or hemispheres and serving to control voluntary movements and coordinate mental actions.
2. the forebrain and the midbrain. |
|
|
Frontal Lobe/Motor Cortex
|
1. motor behavior
2. expressive language 3. higher level cognitive processes 4. orientation to person, place, time, and situation |
|
|
Parietal Lobe/Somatosensory Cortex
|
processing of:
-touch -pressure -temperature -pain |
|
|
Occipital Lobe/Visual Cortex
|
interpretation of visual information
|
|
|
Temporal Lobe/Auditory Cortex
|
-receptive language
-memory -emotion |
|
|
Brainstem
|
-part of spinal cord
-life-sustaining functions -damage to this often fatal |
|
|
Medulla Oblangata
|
-heartbeat
-breathing -blood pressure -digestion -part of the brainstem |
|
|
Reticular Activating System/ Reticular Formation
|
-arousal and attention
-sleep and wakefulness -control of reflexes part of brainstem |
|
|
Pons
|
regulates states of arousal, including sleep and dreaming.
part of brainstem |
|
|
Cerebellum
|
-balance
-smooth movement -posture -part of brainstem |
|
|
Thalamus
|
"central switching station" – relays incoming sensory information (except olfactory) to the brain
part of brainstem |
|
|
Hypothalamus
|
controls autonomic nervous system, and therefore maintains the body’s homeostasis(controls body temperature, metabolism, and appetite. Translates extreme emotions into physical responses.
part of brainstem |
|
|
Limbic System
|
emotional expression, particularly the emotional component of behavior, memory, and motivation
part of brainstem |
|
|
Amygdala
|
attaches emotional significance to info, mediates defensive/aggressive behavior
part of brainstem |
|
|
Hippocampus
|
memory, transfer of info from short-term to long-term memory
|
|
|
Peripheral Nervous System
|
divided into two sub-systems
not a part of brain or brainstem |
|
|
Somatic Nervous System
|
regulates actions of skeletal muscles
mediating voluntary activity |
|
|
Autonomic Nervous System
|
regulates primarily involuntary activity such as: heart rate
breathing blood pressure digestion these activities can be altered either through specific events or through changing our perceptions about a specific experience. further broken down into two systems: Sympathetic and Parasympathetic Nervous Systems. |
|
|
Sympathetic Nervous System
|
"Fight or Flight"
|
|
|
Parasympathetic Nervous System
|
slow acting
controls the calm-down after fight or flight |
