The Brain
The brain is divided into three part called the
forebrain, midbrain, and hindbrain
Glands secrete this substance into the blood stream
Hormones
The two main parts of the nervous system
The central and peripheral systems
The transmission of characteristics from parent to offspring is called
Heredity
The name of the debate where people argue whether the environment has shaped a person or biological traits shape a person
Nature versus Nurture
This section of the brain is the smallest, and is home to only one important system.
the midbrain
The glands located above the kidneys produces 2 hormones that help people cope with stressful situations. These hormones are called
adrenaline and noradrenaline
Each human body has over 100 billion of these, which send signals all over the body
Neurons
Psychologists study genetics because they can have an effect on
The determination of blood type in a child requires how many pairs of genes from the parents
One
Alcohol has the most profound impact on this part of the brain
the reticular activating system
This gland is referred to as the "master gland"
The Pituitary Gland
Which part of the neuron is responsible for receiving messages from others
the dendrite
Humans have 46 of these, combined into 23 pairs
Chromosomes
The peripheral nervous system is broken down into two more systems, one responsible for voluntary movements, and the other for involuntary movements. These two are called
the somatic nervous system, and the autonomic nervous system
This part of the hindbrain is responsible for the regulation of vital functions such as heart rate, blood pressure, and breathing.
the Medulla
The condition hypothyroidism causes the production of too much of this hormone, and leads to these side effects. (2 part answer)
Thyroxin, causes slow metabolism, weight gain
Neurons specifically designed to carry information about the movement of our extremities are called
Motor Neurons
This type of study shows how closely related two people are
A kinship study
Although this was discussed in out ethics section, Dr. Sergio Canavero plans to perform a human head transplant in the near future. The biggest issue is that the technology available today cannot successfully sever and put back together a vital piece of what system of the body?
The Nervous System (spinal cord)
If someone experiences an injury to this art of the brain, they may have a hard time walking strait, and would become uncoordinated
the Cerebellum
Both the male and female reproductive glands produce testosterone and estrogen. What female specific hormone do the ovaries produce to help women get ready for pregnancy by enlarging the breasts
Progesterone
Neurotransmitters are the chemical messengers of the nervous system. Explain how neurotransmitters are transferred from once neuron to the next.
Neurotransmitters are stored in the axon terminal. When a neuron sends a message, a chemical impulse forces the neurotransmitters out of the axon terminal and into the synapse where the dendrites of the next cell receive the message.
Name one trait that Psychologists have proven to be linked to heredity rather than environment
Intelligence, following rules, risk avoidance, aggression, leadership
We discussed three important hormones for male and female reproductive systems (testosterone, estrogen, and progesterone). Name one other female reproductive hormone produced in the pituitary gland.
Prolactin or Oxytocin
