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 tissue makes up the nervous system?
Nervous tissue, also called neural tissue, is the main tissue component of the nervous system. The nervous system regulates and controls bodily functions and activity.
How does the nervous tissue cause action?
When a nerve impulse reaches the muscle the muscle fibre must move. Muscle cells have special proteins that change both their shape and their arrangement in the cell in response to nervous electrical impulses. …
What is the function of nervous tissue quizlet?
The primary function of the nervous system is to collect a multitude of sensory information; process, interpret, and integrate that information; and initiate appropriate responses throughout the body.
What is the main function of epithelial tissue?
Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.
What is the difference between the nervous tissue and nervous system?
Nervous tissue refers to one of the four types of tissues in the animal body, making up the brain, spinal cord, and nerves while nervous system refers to the network of nerve cells and nerves which transmits impulses between parts of the body. Thus, this is the main difference between nervous tissue and nervous system.
What is a nervous tissue give its functions explain the structure of a neuron with a diagram?
Nervous tissue are found in the brain and spinal cord. … Neurons are the structural units of the nervous tissue. These space cells are specialised for the conduction of impulse is over great distances at great speed. All neurones have a cell body called cyton, several dendrites, and an axon.
How does nervous tissue cause action 10?
How does the nervous tissue cause action? ANS. When a nerve impulse reaches the muscle,the muscle fibre must move by changing their shape. this is possible as muscle cells have special proteins that change both their shape and arrangement in the cell in response to nervous electrical impulses.
How does nervous tissue maintain muscle movement?
Movements of the body are brought about by the harmonious contraction and relaxation of selected muscles. Contraction occurs when nerve impulses are transmitted across neuromuscular junctions to the membrane covering each muscle fibre.
What are three main functions of the nervous system give an example of each quizlet?
Terms in this set (3)
- sensory input. when sensory receptors monitor changes that occur both inside and outside of the body.
- integration. when sensory information is interpreted and the appropriate response is taken.
- motor output. response that is performed by effectors- muscles or glands.
What are the 4 main functions of the nervous system?
The four main functions of the nervous system are:
- Control of body’s internal environment to maintain ‘homeostasis’ An example of this is the regulation of body temperature. …
- Programming of spinal cord reflexes. An example of this is the stretch reflex. …
- Memory and learning. …
- Voluntary control of movement.
What is the main function of the nervous system and how is it structured?
The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).
Which type of tissue lines the urinary bladder and what function does the tissue perform?
Unlike the mucosa of other hollow organs, the urinary bladder is lined with transitional epithelial tissue that is able to stretch significantly to accommodate large volumes of urine. The transitional epithelium also provides protection to the underlying tissues from acidic or alkaline urine.
What is the role of the epithelial tissue that lines the trachea and bronchi?
Respiratory epithelial cells line the respiratory tract from trachea to bronchi into bronchioles and alveolar sacs. The primary functions of the respiratory epithelium, depending on their origin, is to moisten, protect the airway tract from potential pathogens, infections and tissue injury, and facilitate gas exchange.
What is the function of simple squamous cells?
Simple squamous epithelium
This type of epithelia lines the inner surface of all blood vessels (endothelium), forms the wall of alveolar sacs in the lung and lines the body cavities (mesothelium). The primary function of simple squamous epithelia is to facilitate diffusion of gases and small molecules.
