Chapter 1: Brain Basics Flashcards
(32 cards)
The largest part of the human brain; associated with higher order functioning, including the control of voluntary behavior.
Cerebrum
Area that controls thinking, perceiving, planning, and understanding language.
Cerebrum
Area of the brain that is divided into two hemispheres: right and left.
Cerebrum.
Bundle of fibers that bridge the two hemispheres and help them communicate.
Corpus callosum
Sheet of tissue covering the outermost layer of the cerebrum.
Cerebral cortex
Because of its gray color, the cerebral cortex is often referred to as…
gray matter
Area of the brain responsible for initiating and coordinating motor movements; higher cognitive skills, such as problem solving, thinking, planning, and organizing; and for many aspects of personality and emotional makeup.
Frontal lobe
Area of the brain involved with sensory processes, attention, and language. Damage to the right side of this area can result in difficulty navigating spaces, even familiar ones. If the left side is injured, the ability to understand spoken and/or written language may be impaired.
Parietal lobe
Area of the brain that helps process visual information, including recognition of shapes and colors
Occipital lobe
Area of the brain that helps process auditory information and integrate information from the other senses.
Temporal lobe
Neuroscientists also believe that this lobe has a role to play in short-term memory through its hippocampal formation, and in learned emotional responses through its amygdala.
Temporal lobe
Area of the brain consisting of the cerebrum, amygdala, basal ganglia, hippocampus, thalamus, and hypothalamus.
Forebrain
Cerebral nuclei located deep in the cerebral cortex that help coordinate muscle movements and reward useful behaviors.
basal ganglia
Area of the brain that passes most sensory information on to the cerebral cortex after helping to prioritize it
thalamus
Area of the brain that is the control center for appetites, defensive and reproductive behaviors, and sleep-wakefulness
Hypothalamus
Area of the brain that consists of two pairs of small hills called colliculi. These collections of neurons play a critical role in visual and auditory reflexes and in relaying this type of information to the thalamus. This area of the brain also has clusters of neurons that regulate activity in widespread parts of the central nervous system and are thought to be important for reward mechanisms and mood.
Midbrain
Area of the brain that includes the pons and the medulla oblongata, which control respiration, heart rhythms, and blood glucose levels.
Hindbrain
Area of the brain with two hemispheres that help control movement and cognitive processes that require precise timing, and also play an important role in Pavlovian learning.
Cerebellum
An extension of the brain through the vertebral column. It uses information from outside sources as reflex responses to pain, for example, and it also relays the sensory information to the brain and its cerebral cortex. It also generates nerve impulses in nerves that control the muscles and the viscera, both through reflex activities and through voluntary commands from the cerebrum.
Spinal cord
Overall the nervous system is a vast biological computing device formed by a network of gray matter regions interconnected by what kind of tracts?
White matter tracts
How does the brain send messages to the spinal cord?
Through peripheral nerves throughout the body that serve to control the muscles and internal organs
The forebrain, midbrain, hindbrain, and spinal cord form this structure.
The central nervous system (CNS)
The brain is protected by the ____, while the spinal cord, which is about 17 inches (43 cm) long, is protected by the _____ ______
Skull; vertebral column
Names of the body’s two nervous systems
Central and Peripheral Nervous System
