What is? The basic cellular unit of the nervous system, the microprocessor of the brain responsible for conducting impulses from one part of the body to another
The Neuron ("Nerve Cells")
What is? Also known as soma; made up of the nucleus and cytoplasm within cell membrane
What is? Transmits signals away from the neuron's cell body to connect with other neurons and cells
Stem or axon
What is? Collect incoming signals from other neurons and send the signal toward the neuron's cell body
What is? Composed of two separate, interconnected divisions. What are they called?
Nervous system: Central Nervous system and Peripheral nervous system
What is? Composed of the spinal cord and the brain
Central Nervous system
What is? Composed of the peripheral nerves that connect the CNS to receptors, muscles, and glands. Includes the cranial nerves just outside the brain stem. Comprises the somatic nervous system and the autonomic nervous system.
Peripheral nervous system
What is? Conveys information from the CNS to skeletal muscles; responsible for voluntary movement
Somatic nervous system
What is? Regulates internal body functions to maintain homeostasis; conveys information form the CNS to smooth muscles, cardiac muscle, and glands; responsible for involuntary movement.
Autonomic nervous system
What is? Divided into the sympathetic nervous system and the parasympathetic nervous system.
Autonomic nervous system
What is? The excitatory division ; prepares the body for stress (fight or flight); stimulates or increases activity of organs
Sympathetic nervous system
What is? Maintains or restores energy; inhibits or decreases activity of organs.
Parasympathetic nervous system
What is? Either categorized as white or gray matter?
What is? composed of nerve cell bodies and dendrites; it is the working area of the brain and contains the synapses, the area of neuronal connection
What is? the myelinated axons of neurons
What is? Structured to contain grooves and dips of corrugated wrinkles within the brain tissue that provide anatomic landmarks or reference points.
Outermost surface of the brain
What is? Small shallow grooves in the outermost surface of the brain
What is? Deeper groves extending into the brain
What is? The raised tissue areas of the outermost surface of the brain
What is? The brain subdivided into
Cerebrum and the brainstem
What is? The largest part of the brain, which is divided into two halves, the right and left hemispheres.
What is? This hemisphere of the cerebrum is dominant in most people
What is? This hemisphere of the cerebrum controls the left sided body functions
What is? Both hemispheres connected by a large bundle of white matter, an area of sensorimotor information exchange between the two hemispheres
Each hemisphere of the cerebrum is divided into how many lobes?
What is? Largest and most developed lobe of the cerebrum
What is? Frontal lobe location that is Responsible for controlling voluntary motor activity of specific muscles
What is? Frontal lobe location that Coordinates movement of multiple muscles
What is? Frontal lobe location that Allows for multimodel sensory input to trigger memory and lead to decision-making
What is? Frontal lobe location of Working memory, reasoning, planning, prioritizing, sequencing behavior, insight, flexibility, judgment, impulse control, behavioral cueing, intelligence, abstraction
Seat of executive functions
