The nervous system is divided into two main parts: the cns (centeral nervous system), which consists of the brain, spinal cord, and the peripheral nervous system, which consists of 12 pairs of cranial nerves and 31 pairs of spinal nerves and their associated ganglion (a collection of cell bodies. By way of the peripheral nervous system (pns), nerve impulses travel to and from the brain through the spinal cord to a specific location in the body the pns is a complex system of nerves that branch off from the spinal nerve roots.
Anatomy of the nervous system central nervous system the nervous system comprises the brain, spinal cord, and nerves the function of all these parts is to participate in the complex communications necessary to coordinate the body’s functions and activities the entire nervous. Basic nervous system anatomy neurobiology of happiness the components • “central” nervous system (cns) – brain – spinal cord • “peripheral nervous system (pns) nervous system is more active when one is happy – the neurotransmitter “oxytocin” correlates with.

Nervous system, organized group of cells specialized for the conduction of electrochemical stimuli from sensory receptors through a network to the site at which a response occurs nervous system: movement of nerve impulsesthe movement of impulses through the nerve cell, involving both chemical and. The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body it is essentially the body's electrical. The vertebrate nervous system: 1 - receives stimuli from receptors & transmits information to effectors that respond to stimulation 2 - regulates behavior by integrating incoming sensory information with stored information (the results of past experience) & translating that into action by way of effectors.
You’ll learn some general anatomy (a roadmap of your body), learn how the arm bone actually connects to the shoulder bone, and how the different organs work together to keep you alive functions of the nervous system motor unit peripheral somatosensation muscle stretch reflex autonomic nervous system upper motor neurons. The nervous system is the master controlling and communicating system of the body every thought, action, and emotion reflects its activity its signaling device, or means of communicating with body cells, is electrical impulses, which are rapid and specific and cause almost immediate responses. Peripheral nervous system (pns) pns is an extent network of neurons that spreads the whole body and is out of bony structures - the skull (cranium) and the vertebral canal (canalis vertebralis) this network consists of somatic & autonomic ports based on functional compartmentalization. Central nervous system (cns) the central nervous system is composed of the brain and spinal cord the brain has 12 cranial nerves the spinal cord, which originates immediately below the brain stem, extends to the first lumbar vertebra (l1.
Regulation of autonomic nervous system activity the efferent nervous activity of the ans is largely regulated by autonomic reflexes in many of these reflexes, sensory information is transmitted to homeostatic control centers, in particular, those located in the hypothalamus and brainstem. The peripheral nervous system consists of the somatic nervous system (sns) and the autonomic nervous system (ans)the sns consists of motor neurons that stimulate skeletal muscles in contrast, the ans consists of motor neurons that control smooth muscles, cardiac muscles, and glands. The anatomy and physiology of the brain the brain and spinal cord form the central nervous system these vital structures are surrounded and protected by the bones of the skull and the vertebral column, as shown in the drawingthe bones of the skull are often referred to as the cranium.
