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 2 main functions of nervous tissue?
Integration and communication are the two major functions of nervous tissue. Nervous tissue contains two categories of cells — neurons and neuroglia. Neurons are highly specialized nerve cells that generate and conduct nerve impulses.
What is the function of nervous tissue for Class 9?
Nervous or the nerve tissue is the main tissue of our nervous system. It monitors and regulates the functions of the body. Nervous tissue consists of two cells: nerve cells or neurons and glial cells, which helps transmit nerve impulses and also provides nutrients to neurons.
What is the function of nervous tissue quizlet?
To maintain body homeostasis with electrical signals, provide for sensation, higher mental functioning, and emotion response, and activate muscles and glands. Central nervous system and Peripheral nervous system. The PNS is divided into somatic and autonomic branches.
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.
Where is nervous tissue found?
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.
Where is nervous tissue not found?
Solution : Tendons are the connective tissue, which join skeletal muscels to bones, hence nervous tissue is absent is them .
What is Class 9 muscle tissue?
Muscular tissue consists of elongated cells, also called muscle fibres. This tissue is responsible for movement in our body. Main function of muscular tissues is to provide movement to the body. Muscles contain special proteins called contractile proteins, which contract and relax to cause movement.
What is tissue class 9?
A tissue is defined as a cluster of cells which are similar in structure and work together to perform a particular function. 2. … The use of tissues in multicellular organisms is to provide structural and mechanical strength as well as to allow division of labour.
What is the function of nerve cell?
Neurons, also known as nerve cells, send and receive signals from your brain. While neurons have a lot in common with other types of cells, they’re structurally and functionally unique. Specialized projections called axons allow neurons to transmit electrical and chemical signals to other cells.
What are the 3 functions of nervous system?
The nervous system has three broad functions: sensory input, information processing, and motor output. In the PNS, sensory receptor neurons respond to physical stimuli in our environment, like touch or temperature, and send signals that inform the CNS of the state of the body and the external environment.
What are the three main functions of a nervous system 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 is the function of muscle tissue quizlet?
What are the five functions of muscle? movement, maintenance of posture and body temp., communication, construction of organs and vessels, and contraction of the heart.
What is nervous system with diagram?
The Central Nervous System is the integration and command center of the body. It consists of the brain, spinal cord and the retinas of the eyes. The Peripheral Nervous System consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect the central nervous system to arms, hands, legs and feet.
What is the purpose structure and function of the central nervous system?
The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
Why is nervous system important?
The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.
