Biological Foundations of Behavior - Chapter 3 Flashcards
Where is the nucleus of a neuron located?
In the center of the cell body.
What is the primary function of the dendrites?
To receive information and send it through the cell body.
The primary function of axons.
Carries info away from cell body.
The route a message takes within a neuron.
Dendrites, cell body, axon.
The physical junction between two neurons.
Synapses or synaptic gaps across which neurotransmitters pass from one neuron to another.
The neurotransmitter which might appear in levels too low if a person is having difficulty sleeping regularly, paying attention in class, and suffering from depression.
Serotonin.
What are the parts of the body affected if you say someone has a condition affecting her central nervous system?
Brain and spinal cord.
The responsibilities of Afferent nerves and Efferent nerves.
Afferent: Sensory nerves.
- Carry information to spinal cord and brain.
- Communicate information about external environment from sensory receptors.
Efferent: Motor nerves.
- Carry information to muscles
- From brain to hands, feet and other areas of the body that allow a person to engage in motor behavior.
The part of the nervous system responsible for essential body functions such as heartbeat, breathing, digestion, sweating, and sexual arousal.
Autonomic Nervous System (internal organs).
The part of the peripheral nervous system that is activated when you are scared.
Sympathetic nervous system (arouses).
Which part of the nervous system responds, resulting in slower heart and respiration rates and less muscular tension, when you meditate?
Parasympathetic nervous system (calms).
If a person’s cerebellum is damaged, what kind of problems would you anticipate that person to have?
Problems with balance and muscle coordination.
If there is damage to the hippocampus what would most likely be impaired?
Memory.
The area in the brain critical for processing visual information.
Occipital Lobe.
The technique used involving placing electrodes on the subject’s head to study brain activity.
Electrical Recording (EEG/Electroencephalogram).
