Tract
What is a bundle of axons in the CNS?
Hypothalamus
What plays a major role in controlling hormone function, emotion, and motivated behaviors?
CNS
What is the PNS outside of?
Nerve
What is a bundle of axons in the PNS?

What is each "ridge" of the brain's surface called?
Sulcus or fissure
What is each "groove" of the brain's surface called?
The outer gray matter and inner white matter
What does the cortex include?

Precentral motor cortex
What contains the motor cortex?
Secondary motor cortex
What is involved in your planning movements and works together with basal ganglia?
Broca's area
What is involved in speech production?
Prefrontal cortex
What is the largest, and one of the most important regions of the human brain?
Psychosurgery
What is the now out-of-favor technique of surgery to treat cognitive and emotional disorders?
Lobotomy
What is a form of psychosurgery that had negative consequences and is now held in disfavor?
Parietal lobe
What is above the lateral fissure and between the central sulcus and occipital lobe?
Somatosensory cortex
What processes the skin senses and detects body movement and position?
Temporal lobe
What is separated from the frontal and parietal lobes by the lateral fissure?
Wernicke's area

Verified questions
engineering
Balloons are often filled with helium gas because it weighs only about one-seventh of what air weighs under identical conditions. The buoyancy force, which can be expressed as $F_b=\rho_{\text {airg }} V_{\text {balloon }}$, will push the balloon upward. If the balloon has a diameter of $12 \mathrm{~m}$ and carries two people, $70 \mathrm{~kg}$ each, find the acceleration of the balloon when it is first released. Assume the density of air is $\rho=1.16 \mathrm{~kg} / \mathrm{m}^3$, and neglect the weight of the ropes and the cage.
biology
Drosophila females homozygous for the third chromosomal genes pink and ebony (the same genes from Problem 16) were crossed with males homozygous for the second chromosomal gene dumpy. Because these genes are recessive, all offspring were wild-type (normal). F1 females were test crossed to triply recessive males. If we assume that the two linked genes, pink and ebony, are 20 mu apart, predict the results of this cross. If the reciprocal cross were made (F1 males—where no crossing over occurs—with triply recessive females), how would the results vary, if at all?
environmental science
Which of the following does NOT drive ocean currents? (a) Salinity, (b) Prevailing winds, (c) Gravity, (d) Temperature, (e) Precipitation.
chemistry
Calculate the aqueous solubility, in moles per liter, of each of the following,\ (a) $\mathrm{BaCrO}_4, K_{\text {sp }}=1.2 \times 10^{-10}$
