Nervous System Pt.1 on QuizRevolution

The nervous system is divided into two parts: The Central Nervous System (CNS) and the Peripheral Nervous System (PNS).

The frontal lobe houses your personality, some of the functions include: problem solving, movement, creativity, judgment, emotions, planning, and reasoning. The frontal lobe is also the largest lobe of the brain.

Cerebrospinal fluid (CSF) is produced mainly by a structure called the choroid plexus which lines the floor of the lateral ventricle and the roof of the third and fourth ventricles.

The parietal lobe is responsible for the processing of nerve impulses related to the senses, such as pain, taste, touch, temperature, and pressure. The parietal lobe also manages some language functions.

The two parts that make up the central nervous system are the brain and the spinal cord. The brain consists of three major parts: the cerebrum, cerebellum, and the brain stem. The spinal cord is made up of bundles of nerve fibers.

There are three types of neurons which include:

• Inter Neurons: they connect two or more neurons
• Motor Neurons: carry impulses from the Central Nervous System (CNS) to glands, muscles, etc.
• Sensory Neurons: receive impulses and alert the CNS

The autonomic nervous system is divided into three parts: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.

A neuron is a cell body with a nucleus, a dendrite and an axon. The dendrite (the microphone on the Nextel phone) receives the information, the axon (the antenna on the phone) transmits signals to other cells. Think of a neuron as a Nextel walkie-talkie cell phone.

The occipital lobe is responsible for vision and for the brain's ability to identify objects.

The somatic nervous system (SNS) is the portion of the peripheral nervous system (PNS) responsible for controlling the muscular system and external sensory receptors. The Autonomic nervous system consists of the motor neurons that control the internal organs.

Some of the other names for central sulcus include central fissure andfissure of Rolando.

The spinal cord and the brain consist of white matter and gray matter. The white matter is made up of bundles of axons covered with a sheath of myelin. The gray matter consists of masses of dendrites and cell bodies, both covered with synapses.

The temporal lobes are responsible for memory, language, hearing, and meaning. They are concerned with processing and interpreting auditory stimuli and they also play a also play a role in learning and emotion.
