What are the two main parts of the nervous system List and describe the parts of a neuron What do motor neurons do what is myelin and the myelin sheath?
Sensory neurons typically have a long dendrite and short axon, and carry messages from sensory receptors to the central nervous system. Motor neurons have a long axon and short dendrites and transmit messages from the central nervous system to the muscles (or to glands).
What are the two parts of the nervous system quizlet?
The Nervous System is divided into two parts. What are they? 1) The CNS (Central Nervous System) and 2) The PNS (Peripheral Nervous System.
What are the two nervous systems and what are their functions?
This system relays information from your brain and spinal cord to your organs, arms, legs, fingers and toes. Your peripheral nervous system contains your: Somatic nervous system, which guides your voluntary movements. Autonomic nervous system, which controls the activities you do without thinking about them.
What are the two classes of cell tissue that make up the nervous system?
Nervous tissue contains two major cell types, neurons and glial cells. Neurons are the cells responsible for communication through electrical signals. Glial cells are supporting cells, maintaining the environment around the neurons.
What is a sympathetic nervous system?
sympathetic nervous system, division of the nervous system that functions to produce localized adjustments (such as sweating as a response to an increase in temperature) and reflex adjustments of the cardiovascular system.
What are the two types of nervous system cells?
Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the “conducting” cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.
What are the two subdivisions of the autonomic nervous system?
The autonomic nervous system, also called the visceral efferent nervous system, supplies motor impulses to cardiac muscle, to smooth muscle, and to glandular epithelium. It is further subdivided into sympathetic and parasympathetic divisions.
What are the 3 main parts of the nervous system?
The central nervous system (CNS) is made up of the brain, cerebellum and the spinal cord.
What are the two primary cells of the nervous system and what do they do quizlet?
What are the two primary cells of the nervous system, and what do they do? Neurons process information and glial cells are to support neurons in a mechanical way.
What are the two types of cells found in the nervous system quizlet?
There are two main cell types: neurons and neuroglia. The nerve cell known as the “functional unit”. Transmits the impulses of the nervous system. Cell body, Axon, and Dendrites.
Which are the parts of autonomic nervous system?
The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.
What are the two major subsystems of the nervous system?
Nucleus
What are the main organs in the nervous system?
Control of body’s interior setting to preserve ‘homeostasis’ An instance of this is the policy of body temperature level.…
What is the hierarchy of the nervous system?
nervous system are the central and peripheral. The former consists of the brain and spinal cord, while the latter is the rest of the nervous system. The brain and spinal cord carry out the bulk of the complex processing, while the peripheral acts as a sort of buffer between the central nervous system and the outside world. The peripheral system can be further
What are parts of the nervous system respond to stimuli?
Introduction to the Central Nervous System. The central nervous system (CNS) is one of the two major subdivisions of the nervous system.
