Ectoderm is one of three germ layers—groups of cells that coalesce early during the embryonic life of all animals except maybe sponges, and from which organs and tissues form. Muscle tissue is responsible for the locomotion and movements of body . All these categories of tissues are organized to form organs and structures of animal body. 4. organ system. The main difference between nervous tissue and nervous system is that the nervous tissue is one of the four types of tissues in animals, making up the nervous system, whereas the nervous system is the complex system of nerves and cells, which coordinate the functions of the body in response to different responses. The structure and location of the nervous system across animals is highly varied. Nervous tissues are made of cells specialized to receive and transmit electrical impulses from specific areas of the body and to send them to specific locations in the body. INTRODUCTION • Tissues of animal are classified into four major categories: epithelial, connective, muscle and nervous tissues. Nervous tissue is the tissue which works in coordinating with the organs of the body by generating impulses. Nerve tissue is composed of neurons, which are specialized cells able to react to stimuli by sending a signal down a long strand of cell known as an axon. They are responsible for the computation and communication that the nervous system provides. The main cell of the nervous system is the neuron. Course Content:. Connective Tissues- Made of various cells that are involved in lending support to the body, connective tissues are namely the fat, bone, blood and cartilage in an animal body. They are electrically active and release chemical signals to target cells. . The evolution of animals, since their first appearance 600 million years ago, has resulted in an extraordinary number and diversity of lifeforms. In the peripheral nervous system the nervous tissue forms the cranial nerves and spinal nerves, which include the sensory and motor neurons. Epithelial Tissue It monitors and regulates the functions of the body. 05. of 10. Eventually, the clump of cells goes through a stage called . Most tissues ( skin ) can reproduce, not nerve cell. 1. Motor function - The third function is the response to the stimuli that causes muscles to contract or glands to secrete. Cells in the nervous tissue of animals transmit signals across a space called a synapse axon nerve dendrite. Nervous and muscle tissue is unique to animals. Nervous tissue, shown in Figure 14, functions in the integration of stimulus and control of response to that stimulus. What are the Four Basic Types of Tissue in Animals. One of the dendrites, called the axon, is . The tissues of multicellular, complex animals are four primary types: epithelial, connective, muscle, and nervous. It consists of neurons, which have two very important basic properties, respectively, excitability and conductivity. Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and . Animal Tissues (MCQs) CBSE Class 9 - Biology. Nervous Tissue. collagen. Nerve cells are called neurons. These tissues combine to form organs—like the skin or kidney—that have specific, specialized functions within the body. The bodies of organisms in the animal kingdom are made up of different types of tissues. Nervous tissue comprises of the nerve cells or neurons. A nerve consists of a neuron and glial cells. Nervous tissue is composed of two types of cells, neurons and glial cells. Multicellular, complex animals have four primary types of tissue: epithelial, connective, muscle, and nervous. Tissues are groups of cells that have a similar structure and act together to perform a specific function. • Although each of the animals usually has these four kinds of tissues, the appearance and . Nervous Tissue The General Plan of the Animal Body Chapter 1 3. Nervous tissue is composed of two types of cells, neurons and glial cells. User: Cells in the nervous tissue of animals transmit signals across a space called a . Nervous tissue meets all structural criteria of epithelial tissue. The nervous system. rest, antibiotics, vaccinations Weegy: Viral infections can cause illnesses as minor as the common cold and as severe . The nervous system is the part of an animal's body that coordinates the voluntary and involuntary actions of the animal and transmits signals between different parts of its body. Nervous tissues are made of cells specialized to receive and transmit electrical impulses from specific areas of the body and to send them to specific locations in the body organized into structures called nerves. Furthermore, nervous tissue contains nerve cells and neuroglia while nervous . Muscle tissue consists of fibers of muscle cells connected together in sheets and fibers. Question: 5. To control the works of different organs of the body and coordinate their activities. The coordination between muscle tissue and nervous tissue can result in very specialized movements (e.g., food procurement, mate pursuit, predator avoidance). each neuron has a single axon leaving the cell body • axon terminals transmit the impulse across a synapse (gap between the axon terminal and the receiving cell) NERVOUS TISSUES: AXON • cells that do not transmit impulses but instead support the activities of the neurons (glial cells or neuroglia) 1. 1. Samples from 6 different species were collected, i.e., 22 dogs, 16 . Neurons are the basic unit of nervous tissue.

It control and coordinates the body functions. The brain and the spinal cord are composed of this neural tissue. Nervous Tissue The General Plan of the Animal Body Chapter 1 3. Characteristic of animals only, nervous coordination is the function of the nervous system. Muscle Tissue Definition. There are four main types of animal tissues: nervous, muscle, connective, and epithelial. . Function: To receive stimuli and create the proper sensation. Complex permanent tissues or conducting tissues provide passage for water and minerals to move up and down the plant. Something that differentiates animals from other organisms is the presence of the nervous tissue and muscular tissue. List of nine major diseases of the nervous system found in animals:- 1. Nervous Tissue | Back to Top. They help in transmitting messages from the brain to various parts of the body and vice versa. Nervous Tissues- Made up of neurons (nerve cells in the brain), these tissues form the entire nervous system, including the spinal cord and the brain. Complete information on Nervous system in Animals. They are responsible for sensing stimuli and transmitting signals to and from different parts of an organism. Epithelial tissue is comprised of layers of tightly packed cells that line the surfaces of the body for protection, secretion, and absorption. They are responsible for the computation and communication that the nervous system provides. Nerve cells, called neurons, are the longest cells of the human body. All nervous tissue is made up of nerve cells or neurons. These tissues can range from being indistinct (as observed in sponges) to being highly complex (as observed in vertebrates). question_answer 7) Irritability and conductivity are maximum developed in. As epithelial duties include sensory reception, protection of the body, and secretion of hormones, nervous tissue performs these functions to a fault, offering general body responsiveness, integration, and chemical transmission. 2. tissues. Once a nerve cell damaged, it cannot heal it. Nervous tissue is the term for groups of organized cells in the nervous system, which is the organ system that controls the movements of the body, sends and transmits signals to and from different parts of the body, and plays a role in controlling the functions of the body, such as digestion. Nervous tissue is composed of two types of cells, neurons and glial cells. Characteristic of animals only, nervous coordination is the function of the nervous system. In animals, groups of closely related cells specialized to perform the same function are called tissues. Nervous tissue consists of two cells: nerve cells or neurons and glial cells, which helps transmit nerve impulses and also provides nutrients to neurons. The word tissue comes from a form of an old French verb meaning "to weave". . The receptors for nervous coordination are generally located in the sense organs at the body surface, while the response in nervous coordination generally involves a gland or muscle. In addition to neurons, specialized cells known as glial cells serve to . Together with extracellular tissue, the glial cells make up the . After birth, nerve cells do not replicate.
