Characteristics of nervous tissue quizlet
What are the characteristics of the nervous tissue?
Nervous tissue contains two categories of cells — neurons and neuroglia. Neurons are highly specialized nerve cells that generate and conduct nerve impulses. Neuroglia are supporting cells that provide physical sport, remove debris, and provide electrical insulation.
What are three major characteristics of the nervous system?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body.

What is the main function of nervous tissue quizlet?
Nervous Tissue sets STIMULI and transmits SIGNALS called NERVE IMPULSES from one part of an animal to another. Nervous Tissue contains Neurons or Nerve cells, as well as support cells called Glial cells.
Which are basic characteristics of a neuron quizlet?
Terms in this set (6)
- Excitability. Produce nerve impulses and respond to stimuli.
- Conductivity. Conduct nerve impulses and send signals.
- Secrection. Secret neurotransmitters.
- Extreme longevity. Last your entire life.
- Amitotic. don’t divide / reproduce.
- High Metabolic rate. Use lots of O2 / glucose.
What are the main function of nervous tissue?
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.
What are the general characteristics of neurons?
A neuron has three main parts: dendrites, an axon, and a cell body or soma (see image below), which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells.
Which of the following is not a characteristic of a neuron?

Which characteristics apply to the autonomic nervous system?
The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, such as the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal.

What are the 5 main parts of the nervous system?
Peripheral Nervous System
- Somatic Nervous System. The somatic nervous system is made up of motor neurons and sensory neurons that help the body perform voluntary activities.
- Autonomic Nervous System. …
- Sympathetic Nervous System. …
- Parasympathetic Nervous System.
What are the three types of nerves?
There are three types of nerves in the body:
- Autonomic nerves. These nerves control the involuntary or partially voluntary activities of your body, including heart rate, blood pressure, digestion, and temperature regulation.
- Motor nerves. …
- Sensory nerves.
What is nervous system and its function?
Your nervous system is your body’s command center. Originating from your brain, it controls your movements, thoughts and automatic responses to the world around you. It also controls other body systems and processes, such as digestion, breathing and sexual development (puberty).
What are the types of nervous tissue?
4.4B: Types of Nervous Tissue
- Neuroglia.
- Astrocytes.
- Microglial Cells.
- Ependymal Cells.
- Oligodendrocytes.
- Satellite Cells.
- Schwann Cells.
- Neurons.
What are the 7 parts of the nervous system?
The central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).
What is the main structure of the nervous system?
The CNS consists of the brain and spinal cord. The brain is protected by the skull (the cranial cavity) and the spinal cord travels from the back of the brain, down the center of the spine, stopping in the lumbar region of the lower back.
What is a nervous tissue composed of?
Nervous tissue is composed of two types of cells, neurons and glial cells. Neurons are the primary type of cell that most anyone associates with the nervous system. They are responsible for the computation and communication that the nervous system provides.
Which of the following describes nervous tissue?
Which of the following describes nervous tissue? It uses electrochemical signals to carry out its function. It supports and reinforces body organs.
