process visual input Occipital lobe Round 1

receive sensations of touch, body position, hearing PARIETAL LOBES DO Round 1

The brain-stem structure that controls breathing and heart rate medulla oblongota Round 1

Lobe of the brain important for hearing Temporal Round 1

Consciousness is controlled by what? multiple parts of the brain Round 1

What are the respective functions of each hemisphere of the brain? left hemisphere – this is essential to language and logic operations right hemisphere – pattern recognition, nonverbal ideation, and emotional processing. Musical and spatial abilities Round 1

Emotions are controlled by what part of the brain? the limbic system or a ring of cortical and noncortical centers around the brainstem mediates primary emotions and attaches emotional “feelings” to survival-related functions Round 1

Language and speech are controlled by what parts of the brain? the frontal lobe (broca’s area) speech Temporal- Wernicke’s area Round 1

Intelligence is associated with this area frontal lobes Round 1

What is a myelin sheath? glia cells that wrap themselves around a neurons axon to protect it and speed up impulses Round 1

What are three main types of glia cells and what do they do? astrocytes, oligodendrocytes, and Schwann cells Astrocytes provide support for neurons. Oligodendrocytes and Schwann cells both form myelin sheaths, oligodendrocytes in the CNS and Schwann cells in the PNS Round 1

What does cerebrospinal fluid do? cushions the brain and spinal cord, brings the cells nutrients, and washes away wastes Round 1

What type of glia cell connects the brain to it’s blood supply? astrocytes Round 1

What do schwann cell produce myelin sheath Round 1

The medulla oblongata, pons, and midbrain are all part of what section of the brain? The brianstem This controls functions such as breathing rate, regulates arousal and sleep, and conducts sensory and motor signals between the spinal cord Round 1

What two types of matter is the cerebrum made out of? white and gray matter Round 1

What does the cerebellum control? Motor, perceptual, and cognitive functions Round 1

What does the band of axons called the corpus callosum do? connects the left and right hemisperes of the brain Round 1

What is the function of the hypothalmus? regulates homeostasis This includes the following functions: feeding, fighting, fleeing, and reproducing. It is also a thermostat, an appestat (adjusts appetite), a thirst center, and regulates circadian rhythms. Round 1

What does the cerebral cortex control? voluntary movement and cognitive functions Round 1

What embryonic part of the brain give rise to the thalamus, hypothalamus, and epithalamus in adults? the diencephalon Round 1

What is the difference between white and gray matter? White matter has myelin sheaths surrounding the neurons and gray matter is just the neurons and their axons Round 1

The cerebellum controls cognitive functions among others. Give two examples of a cognitive function. learning, decision-making, conciousness, and an integrated sensory awareness with surroundings Round 1

What feature of the neocortex (part of the cerebrum) allows humans’ and other mammals’ brains to have a larger surface area? convolutions, or indents Round 1

Unlike the PNS, what can the CNS not do? the CNS cannot repair itself after injury Ex. brain and spinal cord injuries, strokes, and diseases that destroy the neurons (Alzheimer’s and Parkinson’s) Round 2

What is the responsive region at the leading edge of the growing axon called? The growth cone Round 2

True or False: the human does not produce new neurons after birth False Dr. Peter Erickson did an experiment in which he dissected the brains of terminal cancer patients upon their deaths. He found newly divided neurons in the hippocampus of all the patients. Round 2

True or False: Mature neurons cannot divide True new neuron development comes from stem cells that survive in the brain, not mature neurons Round 2

What are four major diseases and disorders of the nervous system? Schizophrenia Depression Alzheimer’s Parkinson’s Round 2

Name 2 characteristics of schizophrenia. 1. 2. 3. 4. 5. 6. Hallucinations Delusions Blunted Emotions Distractibility Lack of Initiative Poverty of Speech Round 2

About what percentage of the population is affected by major depression? 5 percent Round 2

What is Alzheimer’s disease? a mental deterioration, or dementia it is characterized by confusion, memory loss, and a variety of other symptoms Round 2

Name two symptoms or Parkinson’s disease 1. 2. 3. 4. 5. 6. 7. Difficulty initiating movements Slowness of movement and rigidity Masked facial expression Muscle tremors Poor balance Flexed posture Shuffling gait Round 2

Out of Alzheimer’s and Parkinson’s, which one has a higher incidence people over the age of 85? Alzheimer’s The incidence of Alzheimer’s in people over the age of 85 is 35% and Parkinson’s is 5% Round 2

What are three main functions of the nervous system? sensory neurons – receive information from the sensory receptors interneurons – transfer and interpret impulses motor neurons – send appropriate impulses/ instructions to the muscles and glands Round 2

What is a stimulus? the cause of a physical response Round 2

What is an effector? a body part (muscle or organ) that is activated by a stimulus (nerve impulse) Round 2

What does a myelin sheath do? it insulates the nerve it acts much similarly to the insulation on a wire Round 2

What are white and gray matter found? gray matter is the cell body white matter is the filaments in between the cells Round 2

What common ions are found in both the cytoplasm and outside the cell in interstitial fluid? Na+ and K+ Round 2

What is a synapse? a junction between two nerve cells, where the tip of a nerve fiber almost touches another cell in order to transmit signals Round 2

What is proprioception? the sense of relative position of neighboring parts of the body Round 2

What is acetylcholinesterase? an enzyme, present in blood and some nerve endings, that aids the breakdown of acetylcholine (transmitter of nerve impulses) and suppresses its stimulatory effect on nerves Round 2
