The Nervous System
These two structures make up the central nervous system.
What are the brain and spinal cord?
This lobe is concerned with hearing, memory, emotion and speaking.
What is the temporal lobe?
These are chemical substances carrying messages through the body in blood.
What are hormones?
Researchers attempt to find out whether a trait is inherited by studying this kind of twins.
What is identical?
This machine is used to record the electrical activity of large portions of the brain.
What is an electroencephalograph (EEG)?
This white, fatty substance insulates and protects the axon for some neurons.
This lobe is where visual signals are processed.
What is the occipital lobe?
These produce testosterone and these produce estrogen and progesterone.
This type of twins comes from two different eggs fertilized by two different sperm.
What is fraternal?
Doctors use this technique to see which brain areas are being activated while performing tasks.
What is positron emission tomography (PET)?
These are chemical messengers that either excite or inhibit the next neuron.
What are neurotransmitters?
This part of the brain is located at the rear base of the skull and is involved in the most basic process of life. It also includes the cerebellum, medulla, and the pons.
What is the hindbrain?
This is the master gland, located near the midbrain and the hypothalamus, and secretes a large number of hormones.
What is the pituitary gland?
The genetic transmission of characteristics from parents to their offspring.
What is heredity?
Doctors use this to study brain structures and activity.
What is magnetic resonance imaging (MRI)?
This is the space between two neurons.
What is a synapse?
The thalamus and hypothalamus are located in this part of the brain, which is responsible for sensory and motor control.
What is the forebrain?
These glands release epinephrine and norepinephrine into the blood stream when a person is angry or frightened.
What are the adrenal glands?
This refers to environmental factors such as family, culture, education, and individual experiences that affect behavior.
What is nurture (or environment)?
Doctors use this technique to study the brain to pinpoint injuries and brain deterioration.
What is computerized axial tomography (CT)?
This part of the nervous system that controls involuntary activities like heartbeat, stomach activity, etc.
What is the autonomic nervous system?
This structure helps control posture, balance and voluntary movements.
What is the cerebellum?
This gland regulates blood sugar and secretes insulin when needed.
What is the pancreas?
He published Hereditary Genius in 1869 in which he analyzed over 1,000 families of politicians, religious leaders, artists and scholars. He concluded that success ran in families and heredity was the cause.
Who is Sir Francis Galton?
Doctors use this type of imaging to directly observe both the functions of different structures of the brain and which structures participate in specific functions.
What is functional magnetic resolution imaging (fMRI)?
