The Central and Peripheral Nervous Systems. The nervous system can be divided into two major regions: the central and peripheral nervous systems. The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else (Figure 12.2). The brain is contained within the cranial cavity of the skull.

The peripheral nervous system (PNS) consists of all the nerves branching out of the brain and spinal cord ( the central nervous system, CNS). If you imagine the CNS as the main highway, then the PNS forms all the connecting secondary roads. These allow electrical impulses to travel to and from the furthest regions, or periphery, of the human body.

Presentation Transcript. Peripheral Nervous System • Motor or sensory • General (widespread) or specialized (local) • Somatic (outer tube) or visceral (inner tube) Peripheral sensory receptors By location: • Exteroceptors • Sensitive to stimuli arising from outside body • Interoceptors • Or visceroreceptors, from internal viscera.

All of the spinal nerves are combined sensory and motor axons that separate into two nerve roots. The sensory axons enter the spinal cord as the dorsal nerve root. The motor fibers, both somatic and autonomic, emerge as the ventral nerve root. The dorsal root ganglion for each nerve is an enlargement of the spinal nerve.

1. Electrical signals that are transmitted by the neuron are called neural signals. 2. The junction between 2 neurons is called the Synapse. 3. The transmitting cell is called the sensory neuron. 4. The receiving cell is called the motor neuron. 5.

Learn About the Peripheral Nervous System

Key facts about neuroanatomy; Nervous system: Definition: A network of neurons whose main function is to generate, modulate and transmit information between all the parts of the body. Structural divisions: central nervous system (CNS), peripheral nervous system (PNS) Central nervous system: Definition: Neural tissue within the skull and vertebral column that is the integrative and command.

Anatomy Of Nervous System PPT

Peripheral nervous system. Our nervous system is divided in two components: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which encompasses nerves outside the brain and spinal cord. These two components cooperate at all times to ensure our lively functions: we are nothing.

Your peripheral nervous system (PNS) is one of two main parts of your body's 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.

4. Somatic Nervous System the part of the peripheral nervous system responsible for carrying sensory and motor information to and from the central nervous system. derives its name from the Greek word soma, which means "body." responsible for transmitting sensory information as well as for voluntary movement. contains two major types of neurons: sensory neurons (or afferent neurons) - carry.

12. Autonomic Nervous System: (Involuntary) • The ANS is responsible for providing sensory and motor innervation to smooth muscles, blood vessels, glands, and internal organs. As such, it provides a coordinated regulation of visceral and glandular functions, playing a role in maintaining homeostasis.
