Central Nervous System
Consists of the brain and spinal cord
What is the Central Nervous System
Integration and communication
What are the two main functions of the Nervous Tissue
Protective layers of non-nervous tissue surrounding the brain and spinal cord
What are the Meninges
Detect touch, pain, pressure, temperature, and tension on the skin and in internal organs
What are Somatic Senses
White and gray matter
What are the parts of the brain that make up the Central Nervous System
Occipital, Parietal, Frontal, and Temporal
What are the Lobes of the Brain
Highly specialized nerve cells that generate and conduct nerve impulses
What are Neurons
The fluid that protects the brain from blows to the head and neck
What is Cerebrospinal Fluid
Detect the sensations of taste, smell, hearing, equilibrium, and sight
What are Special Senses
Mostly involved in precise motor control and language
What is the Cerebellum
Controls voluntary motor movements
What is the Basal Ganglia
A substance that increases the speed of impulses along the axon of the neuronal fiber
What is Myelin
Fibers that stimulate or activate skeletal muscle
What is a motor or Efferent Fiber
Chemoreceptors, Nociceptors, Thermoreceptors, Mechanorecetors, and Photoreceptors
What are types of Sensory Receptors
The Sympathetic, Parasympathetic, and Enteric of gastrointestinal nervous systems regulate the processes in the body that we cannot consciously influence
What in the Involuntary Nervous System
Secretes neurohormones and influences body temperature, thirst, and hunger
What is the Hypothalamus
Responsible for responding to stimuli
What is a Dendrite
Axons from different spinal nerves come together in different areas
What is a Nerve Plexus
Exteroceptive Senses, detect touch, pressure, and temperature
Proprioceptive Senses, detect changes in muscles, tendons, ligaments, and joint tissues
Visceroceptive Senses, detect changes in the internal organs
What are the Somatic Senses
The area of skin supplied by the sensory fibers of a single dorsal root
What is a Dermatome
Contains circuits that control reflexive responses such as involuntary movements or complex movements such as walking
What is the Spinal Cord
The conducting region of the neuron transmitting impulses away from the cell body
What is the Axon
Nerves attached to the brain
What are the Cranial Nerves
Detection of sensations that permit the central nervous system to produce reactions and maintain body homeostasis
What is the Function of Senses
Charged with coordinating the body's actions by transmitting signals through the network of nerve cells from one body part to the other.
