What are the two major sets of
structures in the brain?
Forebrain and Brainstem
Posterior to the central sulcus you
will find this lobe. What is its name and what is its function?
Parietal Lobe – Goal-directed behavior
Name the subdivisions of the
nervous system? The most complete answer wins!
Central Nervous System
- Brain and spinal cord
Peripheral Nervous System
- Somatic Nervous System
- Autonomic Nervous System
---->Sympathetic Nervous System
---->Parasympathetic Nervous System
What relationship did Aristotle
believe the mind had with the brain?
What relationship did Charles
Darwin believe the mind had with the brain?
What were these two explanations
called?
Aristotle: Mind and Brain were separate >Mentalism
Darwin: Mind and Brain are inseparable >Materialism
What are the implications of
natural selection on brain and behavior?
Both the brain and behaviour
changed bit by bit in animals that evolved to greater complexity
What are the different animal
kingdoms?
- Monera (bacteria)
- Protista (single cells)
- Plantae (plants)
- Fungi (fungi)
- Animalia (animals)
Among animalia,
what types of nervous systems have evolved?
- Nerve Net
- Segmented nerve trunk
- Ganglia
- Chordate system
What are the three main regions of
the brainstem?
Hindbrain
Midbrain
Diencephalon
What do all chordate nervous
systems have in common?
- Bilaterally symmetrical and
segmented
- Brain and spinal cord encased in
cartilage/bone
- “Crossed” organization – Brain hemisphere receives info and controls the opposite side of
body
***- Spinal cord lies behind the heart
and gut***
These primates evolved 5 million
years ago, walk upright and include all forms of humans
Hominids
This refers to the nervous system's
potential for physical or chemical change that enhances its adaptibility
to environmental change and its ability to compensate for injury
Neuroplasticity
What is the meninges and what are
its three layers?
Brain's three layers of protective
tissue
- Dura mater
- Arachnoid layer
- Pia Mater
This “little
brain”
is involved in the coordination of motor and possibly other mental processes
Cerebellum
What are the areas of the nervous
system predominately composed of cell bodies and blood vessels?
Gray Matter
There are four of these cavities in
the brain that contain cerebrospinal fluid. What are each called?
Ventricles
- left and right lateral
- Third and fourth
These are the bumps on the folded
surface of the brain
These are the grooves of the cortex
Gyri & Sulci
What are large collections of axons
coursing together OUTSIDE the CNS called?
What are large collections of axons
coursing together WITHIN the CNS called?
Nerves
Tracts
This part of the cortex lies at the
back of the brain. What is it called and what is its main function?
Occipital Lobe – Visual processing begins here
What are the names of the parts of
the hindbrain?
- Cerebellum
- Reticular Formation
- Pons
- Medulla
What main structures make up the
forebrain?
- Neocortex
(or cerebral cortex)
- Basal Ganglia
- Limbic System
What are the principal structures
of the limbic system?
Amygdala
Hippocampus
Cingulate Cortex
What is the law of Bell and Magendie?
Sensory fibers → Dorsal
Motor fibers → Ventral
This cortex is anterior to the
central sulcus. What is it called and what is its function?
Frontal Lobe – Executive functions, decision making
Who were two of the first
scientists to try to explain what a neuron is?
Golgi and Cajal y Ramon
What are the three basic
subdivisions of the neuron?
- Dendrites
- Cell body (soma)
- Axon
Describe the information flow in a
neuron (as a list)
Dendrite > Cell body > Axon > End Foot
Name the three basic types of
neurons
- Sensory Neurons
- Interneurons
-Motor Neurons
What are the types of glial cells?
- Ependymal cell
- Astrocyte
- Microglial cell
- Oligodendroglial cell
- Schwann cell
What are the main organelles
important for protein production within the neuron?
- Cell membrane
- The Nucleus
- Endoplasmic reticulum
- Golgi Bodies
- Microtubules
What are the functions of the hypothalamus?
- Hormone function
- Feeding
- Sexual behavior
- Sleeping
- Temperature regulation
- Emotional behavior
These proteins, imbedded within the
cell membrane, allow chemicals to move between the intra and intercellular
fluid
Channels, gates and pumps
What is it called when a gene pair
contains either two identical or two different alleles for the same trait?
