The document summarizes the structure and function of the nervous system. It describes that the nervous system is made up of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord, while the PNS contains neurons that connect the CNS to sensory receptors and effector organs. It also explains the basic anatomy and roles of neurons, sensory and motor neurons, and reflex arcs in transmitting signals throughout the nervous system.
Differentiate anatomy and physiology of the human body
List the different systems in the human body
Describe the functions of the different systems of the body
Illustrate the anatomy of each body system
it consist of detailed description about joints, their number and location. we briefly explained about the types of joints with colorful images. easy to understand for students with the help of pictures. language is also simple.it will be helpful for the beginners.

Nervous system is the main system of our body and without the nervous system body will not function. it is control the all over body parts , organ function and body movements. Nervous system contain brain and spinal cord both are work with with each other as a coordinator. nervous system is divided in to two parts central nervous system and peripheral nervous system.
In humans and other higher animals, the central nervous system (CNS) and peripheral nervous system (PNS) collectively form the whole nervous system. The CNS, which serves as the body's control center, includes the spinal cord and the brain. The PNS, a nerve network, links the CNS to various bodily systems.

Understanding the Chemistry Reference Tables Lab w/ KeyRyan Frank
Lab assessment to help students understand how to use the Chemistry Reference Tables. It can be used for all versions, but the 2011 is the version that the key was made for.
Regents Chemistry - Atomic Trends
Includes information about atomic radius, ionization energy, electronegativity and electron affinity. Included are comprehension questions as well.
Note that there is an Atomic Trends table on the Reference Tables for Chemistry Regents that is used for the questions.

Instructions for Submissions thorugh G- Classroom.pptxJheel Barad
This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?
Students, digital devices and success - Andreas Schleicher - 27 May 2024..pptxEduSkills OECD
Andreas Schleicher presents at the OECD webinar ‘Digital devices in schools: detrimental distraction or secret to success?’ on 27 May 2024. The presentation was based on findings from PISA 2022 results and the webinar helped launch the PISA in Focus ‘Managing screen time: How to protect and equip students against distraction’ https://www.oecd-ilibrary.org/education/managing-screen-time_7c225af4-en and the OECD Education Policy Perspective ‘Students, digital devices and success’ can be found here - https://oe.cd/il/5yV
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. Nervous System: a network of nerve cells and
fibers that transmits nerve impulses between
parts of the body.
It acts as a highway for information to travel.
It controls movement in the body and also
converts information for the brain to read
and process.
There are two nervous systems: The Central
Nervous System & The Peripheral Nervous
System.
4. Dendrite: neuron branch which detects stimuli (changes in the
environment)
Cell Body: body of the neuron where normal metabolic activities
occur
Axon: longest branch covered by a myelin sheath(which
provides electrical insulation) -- carries nerve message or impulse
to the axon terminals
Myelin Sheath: provides electrical insulation
Terminal Branches: release nerve chemicals which stimulate
adjacent dendrites on the next neuron or a muscle cell
Neurotransmitters: Nerve chemicals released at terminal brances
5. Sensory Neurons: neurons which only allow
information to travel one way. They can
transmit information from receptors to the brain
and to motor neurons.
Motor Neurons: neurons which only allow
information to travel one way. The transmit
information from the brain and the spinal cord
to the effectors.
6. Associative Neuron: allows the impulse to
go from the Sensory Neurons to the Motor
Neurons
Receptors: any of the sensory organs (eyes,
mouth, skin)
Effectors: muscles or glands
Ganglion: a group of nerve cells
7. Reflex Arc: the path an impulse takes
1. Receptor
2. Sensory Neuron
3. Associate Neuron
4. Motor Neuron
5. Effector
8. The Central Nervous System consists of
the brain and spinal cord.
The Peripheral Nervous System consists of
the neurons.
9. The Spinal Cord is the pathway that
information travels from receptors to the
brain, and from the brain to the effector.
11. Cerebrum: The cerebrum controls
thought, language, reasoning,
perception and voluntary movement.
12. Cerebellum: controls movement,
balance and posture and is divided
into two hemispheres.
13. The Medulla, or Brain Stem, controls
most of the basic functions of life like
breathing, heart rate and blood
pressure.
14. The Hypothalamus controls body temperature,
emotions, hunger, thirst
The Basal Ganglia controls and coordinates
movement.
The PONS connects the brain to the spinal cord.
The Hippocampus is important for memory.
The Thalamus receives sensory information and
movement information.
16. 1. What is the correct path of a reflex arc?
2. Name one function that each of the
following controls: The Medulla, The
Cerebrum
3. Name three parts of a nerve cell.
4. Name one part of the Central Nervous
System.
5. Besides Central, what is the name for the
other nervous system?
6. Give an example of one effector and one
receptor.
17. 1. Receptor → Sensory Neuron → Associative
Neuron → Motor Neuron → Effector
2. Medulla: Any involuntary action
Cerebrum: Thought, Reason, or any voluntary action
3. Axon, Dendrite, Cell Body, Myelin Sheath,
Nodes of Ranvier, Terminal Branches
4. Brain or Spinal Cord
5. Peripheral Nervous System
6. Effector: Any muscle or nerve
Receptor: Any sensory organ (eyes, skin,
etc.)
