What are the 2 main parts categories of the nervous system?

The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).

What are main parts of central 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 are the main components of the central nervous system quizlet?

The central nervous system is that part of the nervous system that consists of the brain, brain stem, and spinal cord.

What are the two main parts of the nervous system and how do they function?

What are the 2 functions of the peripheral nervous system?

Your PNS feeds information into your brain from most of your senses. It carries signals that allow you to move your muscles. Your PNS also delivers signals that your brain uses to control vital, unconscious processes like your heartbeat and breathing.

What are the two main functions of the somatic nervous system?

The somatic nervous system connects the central nervous system with the body's muscles and skin. Its primary function is to control voluntary movements and reflex arcs, while also helping us process the senses of touch, sound, taste, and smell.

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.

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.

What is the central nervous system?

What Is the Central Nervous System? 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 functions of the central nervous system?

The central nervous system's responsibilities include receiving, processing, and responding to sensory information. The brain is an organ of nervous tissue that is responsible for responses, sensation, movement, emotions, communication, thought processing, and memory.

What are the two main parts of the nervous system are the somatic and autonomic nervous systems?

Your somatic nervous system involves things you can consciously sense and do. Your autonomic nervous system works without you thinking about it, running the behind-the-scenes processes that keep you alive. Both are subdivisions of the peripheral nervous system, a subsystem of your overall nervous system.

Which two 2 systems of the body are mainly involved in maintaining homeostasis and communication?

Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.

What causes bad nerves?

What is somatic and autonomic?

Somatic Nervous System is the one that allows conscious (voluntary) control of skeletal muscles. Autonomic N. S. has the unconscious (involuntary) control of the body and it has 2 branches, the Sympathetic and Parasympathetic NS.

Are there more glia or neurons?

Glia are more numerous than nerve cells in the brain, outnumbering them by a ratio of perhaps 3 to 1. Although glial cells also have complex processes extending from their cell bodies, they are generally smaller than neurons, and they lack axons and dendrites (Figure 1.4).

What is CNS somatic and autonomic?

The somatic nervous system consists of nerves that go to the skin and muscles and is involved in conscious activities. The autonomic nervous system consists of nerves that connect the CNS to the visceral organs such as the heart, stomach, and intestines. It mediates unconscious activities.

What is somatic and autonomic sympathetic and parasympathetic?

The somatic nervous system transmits sensory and motor signals to and from the central nervous system. The autonomic nervous system controls the function of our organs and glands, and can be divided into the sympathetic and parasympathetic divisions.

Is sympathetic autonomic or somatic?

The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.

Can the brain function without glial cells?

Although glia cells DO NOT carry nerve impulses (action potentials) they do have many important functions. In fact, without glia, the neurons would not work properly!
