Nervous System II

• Cerebrum
• Cerebellum
• Brain Stem

• frontal
• parietal
• occipital
• temporal
• insula

• motor function
• behavior and emotions
• memory storage
• thinking
• smell

• body sense
• perception
• speech

vision

• hearing
• taste
• integration of emotions
• language comprehension

autonomic functions

• called the "little brain"
• sensor & motor coordination
• balance

grooves on the surface of the cerebrum

ridges on the surface of the cerebrum

• located in frontal lobe
• controls motor output for speech
• located in the left hemisphere

• a general interpretive area for many types of sensory info and may integrate much of the sensory info coming to the cerebral cortex.
• located in the left hemisphere

• posterior to the brain stem
• important to sensory & motor coordination and balance

• medulla oblongata
• pons
• midbrain

responsible for impulses that control heartbeat, breathing and the muscle tone in blood vessels, which controls blood pressure

• superior to the medulla oblongata
• connects the M.O. and the cerebellum to the upper portions of the brain
• plays important role in breathing

• Most superior portion of the brain stem
• acts as a two-way conduction pathway to relay visual and auditory impulses and other info to the cerebrum

• receives sensory info
• contains control systems for vital functions such as blood pressure, heart rate and breathing
• controls the vital functions of life

inflammation of the meninges (covering of the brain and spinal cord)

the layer of gray matter surrounding the white matter in the brain

deep "islands" of gray matter surrounded by white matter throughout the brain

fluid-filled cavities in the brain

thick white band of nerve fibers that connects the two hemispheres of the cerebrum and allows them to communicate and coordinate their activities

• thalamus
• hypothalamus
• pineal body
• pituitary gland

relays and processes information going to the cerebrum

regulates hormone levels, temperature, water-balance, thirst, appetite and some emotions (pleasure & fear); regulates the pituitary gland and controls the endocrine system

responsible for secretion of melatonin (body clock)

secretes hormones for various functions; known as the master gland of the body

• Olfactory
• Optic
• Oculomotor
• Trochlear
• Abducens
• Trigeminal
• Facial
• Vestibulocochlear
• Glossopharyngeal
• Vagus
• Accessory
• Hypoglossal

located in the parietal lobe just posterior to the somatic sensory cortex
