Neurons and nervous systems Communication around the body Neurons - the basic building blocks of the nervous system‚ soecialised to communicate info around the body Three different types of neurons sensory neurons (afferent) : transfer info from the body to the brain Motor neurons (efferent) : transmit info from brain to the body Interneurins : communication b/w sensory and motor neurons Structure communication with a neuron Communication within neurons is an electrochemical process

Unit 1- Maintaining Dynamic Equilibrium II Ch. 12 – The Nervous System (pp. 390-419) 12.1 – Structure of the Nervous System nervous system: a high-speed communication system which delivers information to and from the brain and spinal cord and all over the body. In any nervous system‚ there are 4 main components: (1) sensors: gather information from the external environment (sense organs) (2) conductors: carry information from sensors to modulators or from modulators to effectors (nerves)

Nervous System Review Sheet 1. List three functions of the nervous system and give a specific example of each. • Reception of stimuli from environment (internal or external) and relay of info to CNS (Sensory division of PNS) – e.g. Receptors in your ear send a signal to the brain when the bell rings. • Integration of stimuli to decide on a response (CNS) – e.g. Your brain receives the signal that the bell is ringing‚ along with signals from your eyes that tell you it is time for class

The Nervous System The nervous system is the most complex part of the body‚ as they govern our thoughts‚ feelings‚ and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease‚ stroke‚ accidents‚ etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous

Nervous System Functions of the Nervous System 1. Detect changes and feel sensations 2. Initiate responses to changes 3. Organize and store information Divisions 1. Central Nervous System – brain and spinal cord 2. Peripheral Nervous System – cranial nerves and spinal nerves (relays info to/from the CNS) - Autonomic Nervous System Nerve Tissue – neurons (nerve fibers) and specialized cells (Schwann‚ neuroglia) 1.

Nervous System The two types of the nervous system are the Central nervous system and the peripheral nervous system. They are responsible for integrating‚ processing‚ and coordinating Sensory data and motor commands the central nervous system‚ which interprets sensory input and carry information to maintain homeostasis. CNS can’t be regenerate because a CNS consists of the spinal cord that mean if it’s break the spinal cord is break also. The peripheral nervous system consists of the nerves

The human condition is a term which references our complicated existence by highlighting our ongoing ability to adapt and change both our perceptions and values. Through our mental capabilities of both creativity and imagination‚ humanity is able to achieve a sense of both self-actualisation and liberation‚ resulting in them acting as the core of our existence where‚ without them we would become susceptible to the overwhelming flaws of the human condition. Evidencing this are the three texts‚ ‘Dejection:

The human condition‚ the ongoing balance between good and evil inside people and their environment. This balance and struggle between the three areas affect personal‚ emotional‚ spiritual and mental growth. Similarly‚ humans illustrate a balance between aggression‚ selfishness‚ and lust mixed with compassion‚ love‚ trust‚ and hope. Humans allow for this equilibrium of an imperfect balance between good and evil. Similarly‚ No one’s inherently good nor inherently evil‚ instead attitude‚ purpose‚ and

The nervous system is a very complex system in the body. It has many‚ many parts. The nervous system is divided into two main systems‚ the central nervous system (CNS) and the peripheral nervous system. The spinal cord and the brain make up the CNS. Its main job is to get the information from the body and send out instructions. The peripheral nervous system is made up of all of the nerves and the wiring. This system sends the messages from the brain to the rest of the body. The brain keeps the
