Summary Introduction

To distinguish:

Between the central and peripheral nervous systems and the somatic and autonomic nervous systems.

Introduction:

The nervous system is a network of specialized cells and nerves. It carries various messages to and from the brain and spinal cord to all over the body and transfer signals across different parts of the body. It involves neural tissues comprises blood vessels and connective tissues.

Summary Introduction

To describe:

The autonomous nervous system and its divisions and some examples of activities controlled by each division.

Introduction:

The autonomic nervous system  (ANS) is divided into the sympathetic and parasympathetic nervous system. The sympathetic nervous system causes the secretion and uses of norepinephrine in reaction. This causes the activation of the physiological changes at the time of fight-or-flight responses. Parasympathetic division slowing the heart.

Summary Introduction

To label:

The diagrams of the human brain and spinal cord by naming the principal structures and describing their functions.

Introduction:

The spinal cord has a structure of long rope-like cord. It moves from the beginning of the brain towards the lower back. It is a complex system that contain nerve pathways. It causes the transfer of messages towards the brain from body parts and nerves throughout the body. The brain converted such messages as sensation, for example, pain, hot, and cold.

Summary Introduction

To describe:

The functions that are usually controlled by the left and right halves of the human cerebral hemisphere.

Introduction:

The cerebral hemispheres are the main part of the central nervous system (CNS). The left hemisphere regulates the right side of the body and dominates writing, language comprehension, reading, logical problem solving and mathematical ability. The right hemisphere regulates the left side of the body. It can recognize faces and spatial relations and causes the production of musical and artistic abilities and identify and express emotions.

Summary Introduction

To distinguish: Between short-term and long-term memory.

Introduction:

According to most of the neurologists and psychologists, learning has two phases, that are a short-term memory and long-term memory.
