4 lobes of the brain - Answer-frontal, parietal, temporal, occipital
function of frontal lobe - Answer-The executive, behavior, Personality and emotional
expression, motor Control
Associated with higher order of intellectual activity
If injured - need to learn how to read again
Frontal lobe motor areas - Answer-Primary motor area (precentral gyrus), frontal eye
field, motor speech area (Broca's area)
Where is Broca's area located? - Answer-frontal lobe, left hemisphere - physical aspect
of producing speech NOT cognitive area
precentral gyrus - Answer-the strip of frontal cortex, just in front of the central sulcus,
that is crucial for motor control
parietal lobe - Answer-A region of the cerebral cortex whose functions include
processing information about touch.
parietal (cerebral lobe) - Answer-somatosensory processing area and Gustatory area
gustatory cortex - Answer-area of the brain that receives and interprets tastes from the
tongue
temporal (cerebral lobe) - Answer-A region of the cerebral cortex responsible for
hearing (auditory cortex), gustatory area and olfactory area
Speech areas of brain - Answer-Span temporal, parietal and occipital lobes (usually left
hemisphere)
association areas of cerebral cortex - Answer-Helps to interpret sensory info such as
visual, auditory, somatosensory
, At the sympathetic organ synapse site, the postganglionic neurons release _____ onto
_______ receptors at the effector organ - Answer-NorE
Adrenergic receptor (alpha or beta)
What is the sympathetic nervous system? - Answer-the division of the autonomic
nervous system that arouses the body, mobilizing its energy in stressful situations
gyrus - Answer-A ridged or raised portion of a convoluted brain surface cerebral surface
of brain)
Central Nervous System (CNS) - Answer-consists of the brain and spinal cord
Peripheral Nervous System (PNS) - Answer-the sensory and motor neurons that
connect the central nervous system (CNS) to the rest of the body.
How does the CNS work? - Answer-different parts of the brain control different mental
functions and therefore are related to different mental illnesses i.e. Frontal Lobe controls
organizational thought, body movement, memories, focuses, attention and deals with
problem solving/decision. (schizophrenia, ADHD)
PNS (peripheral nervous system) - Answer-the sensory and motor neurons that connect
the CNS to the rest of the body
PNS (peripheral nervous system) - Answer-cranial nerves and spinal nerves
brain weight - Answer-3 lbs
Nerves - Answer-neural "cables" containing many axons. These bundled axons, which
are part of the peripheral nervous system, connect the central nervous system with
muscles, glands, and sense organs
sensory function of nervous system - Answer-Gathers internal & external environmental
information to CNS
Integrative function of the nervous system - Answer-Makes the decision as to what
needs to be done. "thinking" to CNS
motor function of nervous system - Answer-Effects a change to maintain homeostasis,
brain tells effectors, causes muscles or glands to take action in order to help maintain
homeostasis.
Astrocytes - Answer-Provide structural and metabolic support for neurons. Provide brain
barrier.
