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
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
- Monera (bacteria)
- Protista (single cells)
- Plantae (plants)
- Fungi (fungi)
- Animalia (animals)
what types of nervous systems have evolved?
- Nerve Net
- Segmented nerve trunk
- Chordate system
What are the three main regions of
What do all chordate nervous
systems have in common?
- - Bilaterally symmetrical and
- - Brain and spinal cord encased in
- - “Crossed” organization – Brain hemisphere receives info and controls the opposite side of
- ***- Spinal cord lies behind the heart
- and gut***
These primates evolved 5 million
years ago, walk upright and include all forms of humans
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
What is the meninges and what are
its three layers?
- Brain's three layers of protective
- Dura mater
- Arachnoid layer
- Pia Mater
is involved in the coordination of motor and possibly other mental processes
What are the areas of the nervous
system predominately composed of cell bodies and blood vessels?
There are four of these cavities in
the brain that contain cerebrospinal fluid. What are each called?
- 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?
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
- Reticular Formation
What main structures make up the
- - Neocortex
- (or cerebral cortex)
- Basal Ganglia
- Limbic System
What are the principal structures
of the limbic system?
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?
- Cell body (soma)
Describe the information flow in a
neuron (as a list)
Dendrite > Cell body > Axon > End Foot
Name the three basic types of
- Sensory Neurons
What are the types of glial cells?
- Ependymal cell
- 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
What are the functions of the hypothalamus?
- Hormone function
- Sexual behavior
- Temperature regulation
- Emotional behavior
These proteins, imbedded within the
cell membrane, allow chemicals to move between the intra and intercellular
Channels, gates and pumps
What is it called when a gene pair
contains either two identical or two different alleles for the same trait?
Homozygous and heterozygous
What are some approaches to genetic
- Selective breeding
- Maintaining spontaneous mutations
- Directly manipulating genetic expression
- Chimeeric animals
- Transgenic animals
- Knockout technology
