Type of matter represented By #5.
What is white matter?
Name of the structure indicated by #7.
What is the anterior horn?
Type of nerve tract that carries messages from the brain to effector organs.
What are descending tracts?
The space in the spinal cord that contains cerebrospinal fluid.
What is the central canal?
The part of the white matter (ie – one of the three columns) that carries sensory information to the brain.
What is the dorsal (posterior) column?
The three main parts of the brainstem, from most inferior to most superior.
What are medulla oblongata, pons and midbrain?
Containing pyramids, this subregion of the brainstem is responsible for vital function such as heartrate, blood pressure, breathing, swallowing and many other vital functions for life.
What is the medulla oblongata?
Containing superior and inferior colliculi, this region of the brainstem is primarily involved with relaying information to the auditory and visual cortex.
What is the midbrain?
Meaning “bridge,” this portion of the brainstem relays information between the right and left hemispheres.
What is the pons?
This group of nuclei is responsible for consciousness, and is the group of cells that are manipulated using anesthetics.
What is the reticular formation?
Three main regions of the diencephalon.
What are the thalamus, epithalamus, and hypothalamus?
Structure #5 – this structure is involved in the onset of puberty in humans and migratory patterns in animals.
What is the pineal body?
This part of the diencephalon is the most superior and posterior portion of the diencephalon. It is responsible for our response to odors and also plays a role in the onset of puberty.
What is the epithalamus?
This is the most inferior part of the diencephalon and controls such things as body temperature, hunger and thirst.
What is the hypothalamus?
Represented by #6 on the diagram – this is the main dumping place for all sensory neurons before they are redirected to the appropriate place in the cerebrum.
What is the thalamus?
The four lobes of the cerebrum.
What are the frontal, parietal, temporal and occipital lobes?
The folds and intervening grooves of the brain, in that order.
What are gyri and sulci?
Known as the comparator, this structure within the brain helps with the learning of new motor movements.
What is the cerebellum?
This is the largest part of the brain.
What is the cerebrum?
This fissure separates the brain into left and right halves.
What is the longitudinal fissure?
The left side of the body is controlled by this cerebral hemisphere.
What is the right hemisphere?
This hemisphere of the brain is much more analytical.
What is the left hemisphere?
Organelle within the neuron represented by #6
What is the cell body?
Type of neuronal pathway illustrated above.
What is a reflex arc?
This is the reason why unmyelinated axons are not as effective as myelinated axons.
What is unmyelinated axons do not carry action potentials (or messages) as quickly? They also use more ATP in the process!
FINAL JEOPARDY Genetics
Explain the difference between a autosomal recessive disease and a sex- linked recessive disease.
Autosomal Recessive – must have two recessive alleles on any chromosome other than the 23 rd (sex pair) Sex-Linked Recessive – girls must have two recessive alleles on 23 rd pair, boys only have to have one recessive allele.
