23
Q

A

motor neurons

24
Q

neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputs.

A

interneurons

25
Q

the division of the peripheral nervous system that controls the body’s skeletal muscles. Also called the skeletal nervous system.

A

somatic nervous system

26
Q

the part of the peripheral nervous system that controls the glands and the muscles of the internal organs (such as the heart). Its sympathetic division arouses; its parasympathetic division calms.

A

Autonomic nervous system (ANS)

27
Q

the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations.

A

Sympathetic nervous system

28
Q

the division of the autonomic nervous system that calms the body, conserving its energy.

A

Parasympathetic nervous system

29
Q

a simple, automatic response to a sensory stimulus, such as the knee-jerk response.

A

reflex

30
Q

The body’s “slow” chemical communication system; a set of glands that secrete hormones into the bloodstream.

A

Endocrine system

31
Q

a pair of endocrine glands that sit just above the kidneys and secrete hormones (epinephrine and norepinephrine) that help arouse the body in time of stress.

A

Adrenal glands

32
Q

the endocrine system’s most influential gland, Under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands.

A

Pituitary gland

33
Q

Tissue destruction. A brain lesion is a naturally or experimentally caused destruction of brain tissue.

A

Lesion

34
Q

an amplified recording of the waves of electrical activity that sweep across the brain’s surface. These waves are measured by the electrodes placed on the scalp.

A

electroencephalogram (EEG)

35
Q

a visual display of the brain activity that detects where a radioactive form of glucose goes while brain performs a given task.

A

PET (positron emission tomography) scan

36
Q

a technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue. MRI scans show brain anatomy.

A

MRI (Magnetic resonance imaging)

37
Q

a technique for revealing bloodflow and, therefore, brain activity by comparing successive MRI scans. FMRI scans show brain function.

A

fMRI (fuctional MRI)

38
Q

the oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skill; the brainstem is responsible for automatic survival functions.

A

brainstem

39
Q

the base of the brainstem; controls heartbeat and breathing.

A

medulla

40
Q

the brain’s sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla.

A

thalamus

41
Q

a nerve network that travels through the brainstem and plays an important role in controlling arousal/

A

reticular formation

42
Q

the “little brain” at the rear of the brain-stem; functions include processing sensory input and coordinating movement-output and balance.

A

cerebellum

43
Q

neural system (including the hippocampus, amygdala, and hypothalamus) located below cerebral hemispheres; associated with emotions and drives.

A

limbic system

44
Q

two lima-bean-sized neural clusters in the limbic system; linked to emotion.

A

amygdala

45
Q

a neural structure lying below (hypo) the thalamus; it directs several maintenance activities (eating, drinking, body temperature), helps govern the endocrine system via the pituitary gland, and is linked to emotion and reward.

A

hypothalamus

46
Q

cells in the nervous system that support, nourish, and protect neurons; they may also play a role in learning and thinking.

A

glial cells (glia)

47
Q

portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movements and in making plans and judgments.

A

frontal lobes

48
Q

portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body position.

A

parietal lobes

49
Q

portion of the cerebral cortex ling at the back of the head; includes areas that receive information from the visual fields.

A

occipital lobes

50
Q

portion of the cerebral cortex lying roughly above the ears; includes the auditory areas, each receiving information primarily from the opposite ear.

A

temporal lobes

51
Q

area at the front of the parietal lobes that registers and processes body touch and movement sensations.

A

sensory cortex

52
Q

areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking.

A

association areas

53
Q

the brain’s ability to change, especially during childhood, by reorganizing after damage or by building new pathways based on experience.

A

plasticity

54
Q

the formation of new neurons.

A

neurogenesis

55
Q

the large band of neural fibers connecting the two brain hemispheres and carrying messages between them.

A

corpus callosum

56
Q

a condition resulting from surgery that isolates the brain’s two hemispheres by cutting the fibers (mainly those of the corpus callosum) connecting them.

A

split brain
