Transcript of THE BRAIN!!!!

Cerebellum Functions coördinates sensory input from the inner ear and the muscles to provide accurate control of position and movement
plays a major role in adapting and fine-tuning motor programs to make accurate movements through a trial-and-error process
Due to its role in the coordination of fine motor movements the cerebellum makes important contributions to the control of rapid, alternating muscle movements necessary for speech. Temporal Lobe Responsible for
-memory
-speech
-reading
-emotions
-auditory
-visual Functions processing information relating to the sense of touch
visuospatial processing
The posterior parietal cortex (PPC) receives somatosensory and/or visual input, which then, through motor signals, controls movement of the arm, hand, as well as eye movements Functions Limbic System Under the Cerebrum
Responsible for
-emotion
-behavior
-motivation
-long term memory Communication Between Brain Hemispheres
Eye Movement
Maintaining the Balance of Arousal and Attention
Tactile Localization -Sulci are the folds in the brain.
-Gyri are the area between the folds.
-Responsible for conservation of space within the brain- Control center for behavior
Center for function, language, & motor control
Most vulnerable to injury because of placement in the brain Occipital Lobe Contains visual information and color recognition
Posterior of the temporal lobe, anterior of the parietal lobe Cerebrum Contains perception, imagination, thought, judgement and decision occurrence
Composed of six layers of neurons
contains about 10 million neurons and 50 trillion synapse Have "valleys" that form boundaries between the four lobes Main functions include:
Motor control
Receive auditory, somatosenorsy and visual sensory signals
Relax sensory signals
Control awake and sleep states Consists of lamellae that separate different sub parts Controls automatic nervous system
Contains the thirst and hunger center and body's thermostat
Emotions that can effect the body- e.g. the butterflies
Controls pituitary gland Pituitary Gland Growth Hormone Production
Production of hormones that act on the endocrine system and hormones that act on the muscle and kidneys
Storage of Hormones produced by Hypothalmus Protects the brain and spinal cord
Responsible for nourishing the brain
Provides cushioning effects for the CNS
Supports channels that carry blood from the brain toward the heart Absorbs physical shock in the brain
Removes waste from soft tissue
Provides a chemically stable environment in the brain Temporal Lobe On either side of the brain
Above the ears Control center for speech, process comprehension, and verbal memory
Reading, emotions, auditory, and visual Sensory and Motor Areas Located in the frontal part of the partial lobe- middle of the brain
Receives info from spinal cord about sense of touch, pressure, pain etc.
Located in mid brain
top controls movement in various body parts Contains Hypothalamus and thalamus
On and under brain steam Either side of thalamus
Under the Cerebrum
Control center for emotions, behavior, motorization and long term memory Medulla Oblongata
Located at the bottom of the brainstem
Responsible for
-respiration
-blood pressure
-motor functions
-body secretions
-swallowing
-reflexes Reticular Formation
-central area of brainstem
-obtains recuperative sleep
-responsible for sexual arousal
-focusing Sulci are the wrinkles found within the brain,
Gyri are the ridges between the folds.
These are found all throughout the brain.
These allow more matter to be packed into the skull. Sulci & Gyri Parietal Lobe Functions Involved in
movement
orientation
recognition
perception of stimuli Functions Communication Between Brain Hemispheres
Eye Movement
Maintaining the Balance of Arousal and Attention
Tactile Localization Pons and Midbrain vision
hearing
eyemovement
body movement Functions regulation
coordination of movement
posture
balance. Cerebellum Functions regulation and coordination of movement
posture
balance Functions Functions Consolidation of New Memories
Emotional Responses
Navigation
Spatial Orientation Controls Cognition
Movement Coordination
Voluntary Movement Functions
