What are the major components of the nervous tissue?

Nervous tissue is composed of neurons, also called nerve cells, and neuroglial cells. Four types of neuroglia found in the CNS are astrocytes, microglial cells, ependymal cells, and oligodendrocytes. Two types of neuroglia found in the PNS are satellite glial cells and Schwann cells.

What are the two components of the central nervous system Nasm?

The CNS, central nervous system, is comprised of two things, the brain and the spinal cord.

What are the two main communication systems of the body?

Humans have two types of communication systems. These are the nervous system and the endocrine (hormone) system. These systems regulate body processes through chemical and electrical signals that pass between cells.

What are the two main components of the central?

The main components of central nervous system are the brain and the spinal cord.

What are the two parts of the brain called?

The cerebrum, which forms the major portion of the brain, is divided into two major parts: the right and left cerebral hemispheres. The cerebrum is a term often used to describe the entire brain. A fissure or groove that separates the two hemispheres is called the great longitudinal fissure.

What are the two ways in which the brain is protected?

The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.

What are the 3 parts of the nervous system?

The human nervous system is made up of three basic parts: the central nervous system, the peripheral nervous system, and the autonomic nervous system. Without a doubt, it is the most complex part of the human body, a masterpiece of nature.

Where do action potentials begin?

A typical action potential begins at the axon hillock with a sufficiently strong depolarization, e.g., a stimulus that increases V_m.

Which nerves carry messages to the brain?

Motor nerve carries messages to the brain.

What will you do in order to maintain your major organs healthy?

What are the parts of the nervous system and their functions?

The Brain and Spinal Cord Are the Central Nervous System. Nerves and Sensory Organs Make Up the Peripheral Nervous System. Together, the central nervous system (CNS) and the peripheral nervous systems (PNS) transmit and process sensory information and coordinate bodily functions.

What are the 2 components of the central nervous system and what is their function?

The central nervous system is made up of the brain and spinal cord: The brain controls how we think, learn, move, and feel. The spinal cord carries messages back and forth between the brain and the nerves that run throughout the body.

What are the two main physical components of the central nervous system quizlet?

Central nervous system includes brain and spinal cord.

What are the main components of the nervous system quizlet?

What are the 3 components of the human nervous system quizlet?

The human nervous system can be divided into the central nervous system consisting of the brain and the spinal cord and the peripheral nervous system, consisting of all nerves outside the CNS. The PNS carries information to and from the CNS to the body.

What is the main function of the nervous system quizlet?

The main functions of the central nervous system is to PROCESS information received through sensory systems and other parts of the body and to activate appropriate actions to the external/internal stimuli.
