Chapter 14 - Parts Of The Brain Flashcards
Plays a role in regulating heart rate, in responding to fear and anxiety and controlling the “fight or flight” response by the sympathetic division of the ANS, and in linking emotions with specific memories.
Amygdala
Consists of the Left and Right Thalamus and the Hypothalamus
Dicencephalon
Processing of visual and auditory data, generation of reflexive somatic motor responses, maintenance of consciousness
Midbrain
Directs voluntary movements by controlling somatic motor neurons in the brain stem and spinal cord
Primary motor cortex
Has extensive connections with other cortical areas and with other portions of the brain. Feelings of frustration, tension, and anxiety are generated as this region interprets ongoing events and makes predictions about future situations or consequences.
Prefrontal cortex
Relays sensory information to cerebellum and thalamus, subconscious somatic and visceral motor centers
Pons
Relays sensory information to thalamus and to other portions of the brain stem, autonomic centers for regulation of visceral function (cardiovascular, respiratory, and digestive system activities)
Medulla Oblongata
One of the reflex centers of the Medulla Oblongata which sets the basic pace for respiratory movements
Respiratory rhythmicity centers
One of the reflex centers of the Medulla Oblongata which adjusts the heart rate, the strength of cardiac contractions, and the flow of blood through peripheral tissues
Cardiovascular centers
Involved with the subconscious control of skeletal muscle tone and the coordination of learned movement patterns. Under normal conditions do not initiate particular movements, but once a movement is under way they provide the general pattern and rhythm
Basal nuclei
You are aware of sensations only when nuclei in the thalamus relay the information to this area of the brain
Primary sensory cortex
Conscious thought processes, intellectual functions, memory storage and processing, conscious and subconscious regulation of skeletal muscle contractions
Cerebrum
Important in learning, especially in the storage and retrieval of new long-term memories
Hippocampus
Consists of the midbrain, pons, and medulla oblongata
Brain Stem
Relay and processing centers for sensory information
Thalamus
