The nervous system consists of the brain, spinal cord, nerves, and sense organs. It receives information from inside and outside the body, responds to stimuli, and maintains homeostasis. The central nervous system contains the brain and spinal cord, which act as the control center. The peripheral nervous system branches out from the central nervous system via nerves that connect to the rest of the body in 43 pairs, controlling both voluntary and involuntary actions.

Unit 1 interaction no.1
The document discusses the functions of the nervous system. It states that the nervous system sends messages from the brain to different parts of the body to allow responses to stimuli from the senses. It also controls internal systems like digestion and respiration. The brain is the most important organ as it controls the nervous system and processes information from the senses. It is made up of the cerebrum, cerebellum and brain stem which control cognitive thinking, movement and involuntary functions respectively. The spinal cord runs from the brain down the spine and controls reflex actions.

The nervous system includes the brain, spinal cord, and network of nerves. It controls and regulates bodily functions from basic activities like breathing to complex processes like thinking. The nervous system is made up of nerves that carry signals between the brain and spinal cord, as well as the brain and spinal cord themselves. A healthy nervous system is supported by regular exercise, a balanced diet, deep breathing, and walking barefoot on earth.
The Nervous System At A Glance
The nervous system is responsible for coordinating all body activity and is divided into the central nervous system and peripheral nervous system. The central nervous system consists of the brain and spinal cord and controls everything in the body. It is made up of over 10 billion nerves and is divided into the cerebrum, cerebellum, and brain stem, each controlling different functions like thinking, balance, and heartbeat. The peripheral nervous system is made of nerves and sense organs and carries messages between the central nervous system and the rest of the body.
Nervous System Notes
The nervous system is made up of the brain, spinal cord, and nerves. It receives information from both inside and outside the body through sense organs and responds by directing the body to maintain homeostasis. The central nervous system contains the brain and spinal cord as the control center. The peripheral nervous system consists of nerves that branch out from the central nervous system and connect to the rest of the body in 43 pairs, controlling both voluntary and involuntary actions.
The nervous system
This document discusses the nervous system and how it controls and regulates the body. It describes how neurons send and receive signals through electrical and chemical processes. The nervous system consists of the central nervous system (brain and spinal cord) and peripheral nervous system. The peripheral system includes cranial and spinal nerves that connect to muscles and organs. Sensory neurons receive signals from stimuli and motor neurons send signals to muscles and glands. The nervous system maintains homeostasis through reflexes and control systems that regulate vital functions like breathing and heart rate.
The nervous system
The document discusses the nervous system and its key components and functions. It is divided into three main parts:
1. The central nervous system (CNS) which controls all body activities and consists of the brain and spinal cord.
2. The peripheral nervous system which connects the CNS to the rest of the body via nerves and sense organs like the skin, eyes, and tongue.
3. The autonomic nervous system which controls involuntary body functions like breathing and heart rate.
Functions of nervous system
The nervous system has four major functions:
1. Somatic function allows for voluntary movement through electrical signals that cause muscle contraction.
2. Sensory function involves sense organs picking up external and internal stimuli which the brain interprets.
3. Autonomic function involuntarily controls internal organs like the heart and lungs without conscious thought.
4. Cognitive function enables problem-solving and learning through mental processing, distinguishing humans from animals.
The document provides examples of how these functions interact in the nervous system to allow Jose to avoid an oncoming car through sensory perception, involuntary heart rate increase, cognitive processing, and voluntary movement.

Nervous systems by julia and cameron
The nervous system has two main parts - the central nervous system comprising the brain and spinal cord, and the peripheral nervous system made up of nerves throughout the body. The nervous system passes messages to and from the brain via nerves, allowing it to receive sensory information and control the body's movements. It is essential for functions like sensing hunger, pain, temperature and coordinating movement.
Nervous System In Humans
The document summarizes the nervous system in humans. It describes the central nervous system as including the brain and spinal cord. The peripheral nervous system has nerve cells with axons that extend through the limbs. The peripheral nervous system has three divisions: somatic, sympathetic, and parasympathetic. Neurons transmit nerve messages while glial cells support and protect neurons. Neurons receive signals at dendrites, transmit signals along axons, and communicate between cells via neurotransmitters at synapses.

I do not have enough information to make a claim about Homer's brain or what it can coordinate. The document provided is a general overview of the human nervous system and does not mention Homer.
Peripheral Nervous System
The peripheral nervous system consists of all nervous tissue outside the central nervous system and has two main components: cranial and spinal nerves, and sensory receptors. It has two functional subdivisions - the sensory (afferent) division which transmits signals from receptors to the CNS, and the motor (efferent) division which transmits signals from the CNS to effector organs like muscles and glands. The motor division contains the somatic nervous system which controls skeletal muscles, and the autonomic nervous system which regulates involuntary functions and contains the sympathetic and parasympathetic systems.
Nervous System
The nervous system is made up of the brain, spinal cord, and network of nerves. It processes information as the body's internal communication system. Neurons are the basic unit, carrying electrical signals throughout the body. The central nervous system includes the brain and spinal cord, which process sensory information. The peripheral nervous system connects to the central nervous system and controls involuntary functions. It is divided into the somatic and autonomic systems. The autonomic system further divides into the sympathetic and parasympathetic systems which work in opposition to activate the fight or flight response or return the body to rest.
Ch2 psy
The document discusses two major communication systems in the body - the nervous system and the endocrine system. The nervous system uses neurons and electrochemical signals to transmit information quickly. It has two parts - the central nervous system (brain and spinal cord) and the peripheral nervous system (rest of body). The endocrine system is slower acting but influences behaviors like sleep, eating, growth and sexuality through chemical messengers called hormones secreted by glands like the pituitary, thyroid, adrenals, pancreas, testes and ovaries. The document also notes that both genetic and environmental factors (nature and nurture) influence traits and personality.

Brain and cranial nerves.
Spinal cord and motor and sensory pathways of the spinal cord, autonomic nervous system.
Nervous system:
Nervous system is one of vital system in our body which control and coordinate all the functions of body parts.
Classification:
Central nervous system (CNS)
Peripheral nervous system (PNS)
1. Central nervous system (CNS): brain and spinal cord
2. Peripheral nervous system (PNS): Somatic nervous System & Autonomic nervous system (ANS)
Central Nervous System (CNS):
The central nervous system (CNS) controls most functions of the body and mind.
It consists of two parts: the brain and the spinal cord.
The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
It interprets information from our special senses, as well as from internal organs
Meninges:
The coverings of brain and spinal cord are called meninge.
There are 3 layers surrounding the brain and spinal cord.
Dura (outer layer)
Arachnoid (middle layer)
Pia matter (inner layer)
Dura mater: The tough outer layer is called the dura mater. protect the central nervous system.
Arachnoid: The middle layer is the arachnoid, It contains cerebrospinal fluid, which acts to cushion the brain
Pia matter: the innermost layer of the meninges, the pia mater closely covers the brain.
Brain:
Introduction:
The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body.
the brain and spinal cord Together make up the central nervous system, or CNS
The brain receives information through our five senses: sight, smell, touch, taste, and hearing - often many at one time
Diagram:
Structure:
The brain is composed of the cerebrum, cerebellum, and brainstem
Cerebrum (telencephalon or endbrain): is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.
Cerebellum (little brain): is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance.
Brainstem: consist midbrain, the pons, and the medulla oblongata acts as a relay center connecting the cerebrum and cerebellum to the spinal cord.
Functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing.
Lobes of the brain:
Each hemisphere has 4 lobes:
Frontal lobe
Temporal lobe
Parietal lobe
Occipital lobe
Each lobe may be divided, once again, into areas that serve very specific functions
The cerebral cortex has many folds, called the gyrus (plural: "gyri") and its trough is called a sulcus (plural: sulci)

The central nervous system receives sensory information and controls responses through the brain and spinal cord. It is divided into the forebrain, midbrain, and hindbrain. The peripheral nervous system connects the central nervous system to the rest of the body through nerves and is divided into the somatic and autonomic systems. Common nervous system diseases include Alzheimer's disease, which causes memory loss and cognitive decline, and epilepsy, which involves seizures.
THE NERVOUS SYSTEM.pptx
The nervous system controls and regulates the functions of the body. It has three main parts: the brain, spinal cord, and nerves. The central nervous system consists of the brain and spinal cord and processes information from the body. The peripheral nervous system is made up of nerves branching from the spinal cord to all parts of the body and relays information between the brain and rest of the body. It has sub-parts that control involuntary functions and regulate movement.
C)nervous system
The document discusses the structure and function of the nervous system. It describes that the nervous system controls and regulates all functions of the body. It is made up of the central nervous system (brain and spinal cord) and peripheral nervous system. The central nervous system includes the brain parts like cerebrum, cerebellum, medulla, and diencephalon. The cerebrum controls higher functions while the cerebellum coordinates movement. The peripheral nervous system includes the somatic and autonomic systems. The autonomic system further divides into the sympathetic and parasympathetic systems which work to stimulate or relax the body. Exercise is beneficial for the nervous system by reducing anxiety and depression and increasing blood flow to the brain.
Nerves system(CNS, PNS)
“The right half of the brain controls the left half of the body. This means that only left handed people are in their right mind.”

Made up of all the nerves that carry messages to and from the central nervous system.Similar to telephone wires that connect all of our houses in the communityCentral Nervous System and Peripheral Nervous System work together to make rapid changes in your body in response to stimuli.Peripheral Nervous System is green in this diagram.
Somatic Nervous SystemRelay information between skin, skeletal muscles and central nervous systemYou consciously control this pathway by deciding whether or not to move muscles (except reflexes)Reflexes: Automatic response to stimulusAutonomic Nervous SystemRelay information from central nervous system to organsInvoluntary: You do not consciously control theseSympathetic Nervous System: controls in times of stress, such as the flight or fight responseParasympathetic Nervous System: controls body in times of rest
parasympathetic unit IV.pptx
The peripheral nervous system (PNS) consists of nerves branching from the brain and spinal cord that allow electrical impulses to travel between the central nervous system and the rest of the body. It is divided into the somatic nervous system and autonomic nervous system. The somatic nervous system controls voluntary activities through spinal and cranial nerves. The autonomic nervous system regulates involuntary functions through the sympathetic and parasympathetic divisions.
NERVOUSSYSTEM.pptx
The nervous system is made up of the central nervous system (CNS) and peripheral nervous system (PNS). The CNS contains the brain and spinal cord, and receives and processes all sensory information. The brain is divided into three main parts and is responsible for controlling functions like temperature, appetite, and emotions. The PNS connects the CNS to the rest of the body and contains somatic and autonomic systems, with the autonomic system regulating involuntary functions and being divided into sympathetic and parasympathetic systems. The nervous system allows all parts of the body to communicate and respond to internal and external changes.

Third Quarter Lesson for Science 10.
the nervous system is the highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body.
Quarter3_Module3.pptx
The central nervous system consists of the brain and spinal cord. The brain is organized into three main parts - the cerebrum, cerebellum, and brain stem. The spinal cord carries signals between the brain and body.
The peripheral nervous system connects the central nervous system to organs and limbs. It has two main divisions - the somatic and autonomic nervous systems. The autonomic nervous system regulates involuntary body functions and has two parts: the sympathetic and parasympathetic nervous systems.
The basic unit of the nervous system is the neuron, which carries electrical signals through an axon and dendrites to communicate with other neurons. The nervous system works with the endocrine system to maintain homeostasis through regulating vital body
Nervous system
The nervous system coordinates the body's actions and sensory information. It is composed of the brain, spinal cord, nerves, and ganglia. The nervous system has three main functions - sensory, which detects stimuli; integrative, which processes sensory information; and motor, which causes muscle and gland responses. It is divided into the central nervous system of the brain and spinal cord, and the peripheral nervous system of nerves and ganglia. The peripheral system connects the central system to the body and is divided into the autonomic and sensory systems. Neurons are specialized cells that conduct nerve impulses.

The nervous system consists of the central nervous system (brain and spinal cord) and the peripheral nervous system. The central nervous system processes information from the senses and controls and coordinates the body's activities, while the peripheral nervous system connects the central nervous system to the limbs and organs. Key components include neurons, which transmit signals; the brain, which controls the body's responses; and the spinal cord, which connects the brain to the rest of the body. The nervous system allows for voluntary and involuntary responses through reflex arcs that transmit signals from sensors to effectors.
nervous system
The document discusses the structure and function of the nervous system. It describes how the central nervous system, made up of the brain and spinal cord, coordinates the body's activities through the neurons. The peripheral nervous system connects to and relays messages from the central nervous system through sensory neurons, motor neurons, and interneurons. The three main sections of the brain - the cerebrum, cerebellum, and brainstem - each have distinct roles in controlling voluntary movement, balance, and involuntary functions. Major nervous system diseases and their prevalence and economic costs are also listed.

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Top-Vitamin-Supplement-Brands-in-India List

- 2. What makes up the Nervous System? • Brain • Spinal cord • Nerves • Sense Organs (eyes, ears, nose, tongue, skin)
- 3. What are the jobs of the Nervous system? 1. Receive information – both inside and outside your body (Ex: Wind blowing, low glucose in your blood) 2. Responds to information – reacts to stimuli (Ex: soccer ball comes toward you – you kick the ball) 3. Maintains homeostasis – directs the body to respond to information (Ex: hungry – eat, thirsty – drink)
- 4. Central Nervous System • The Central nervous system contains the BRAIN and the SPINAL CORD. • The CNS is like the CONTROL CENTER of our bodies. • The BRAIN allows us to control most of the functions in our bodies • The SPINAL CORD connects our brain to our nerves.
- 6. Peripheral Nervous System The peripheral nervous system consists of a network of NERVES that branch out from the CENTRAL NERVOUS SYSTEM and CONNECT to the rest of the BODY.
- 7. Peripheral Nervous System A total of 43 pairs of nerves make up the entire PNS. 12 pairs of nerves originate from the brain. 31 pairs of nerves begin in the spinal cord.
- 9. Two Groups of the PNS Somatic Nervous System – controls voluntary actions Ex: Using a fork, tying your shoelaces Autonomic Nervous System – controls involuntary actions Ex: heartbeat, breathing
- 10. Analogy The central nervous system is like _________, while the nerves of the peripheral nervous system is like the ______________.
