The document discusses the nervous system and endocrine system, which are two key systems that control the human body. The nervous system uses neurons and electrical signals to control and coordinate fast, short-term responses, while the endocrine system relies on glands and hormones to bring about slower, longer-term changes through the bloodstream. Students are asked to study these two systems, focusing on the structure and function of neurons, reflex arcs, and how stimuli trigger responses through the nervous system.

The nervous system is the body's communication network, coordinating and regulating all bodily functions. Comprising the central nervous system (CNS) and peripheral nervous system (PNS), it consists of neurons, specialized cells transmitting electrical and chemical signals. The CNS, consisting of the brain and spinal cord, interprets and processes information. The PNS extends from the CNS, transmitting signals between the brain, spinal cord, and the rest of the body. Sensory neurons detect stimuli, while motor neurons control muscle movement. This intricate system enables sensory perception, voluntary and involuntary actions, and regulates bodily processes, ensuring homeostasis and facilitating responses to the environment.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.

Normal Labour/ Stages of Labour/ Mechanism of LabourWasim Ak
Normal labor is also termed spontaneous labor, defined as the natural physiological process through which the fetus, placenta, and membranes are expelled from the uterus through the birth canal at term (37 to 42 weeks
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. The Body Control Systems
You are made up of somewhere between 50 000 000 000
000 – 75 000 000 000 000 (50 – 75 Trillion cells1.
To maintain and control all of these we have a number of
systems this year we will look at 2 of these.
1. Asimov, Isaac, The Human Body, New Rev Ed. p 79
3. In this Unit We will look at two systems involved in the
control of the Human Body:
1. The Nervous System 2. The Endocrine System
Consists of tissues that Consists of glands that produce
conduct electrical signals chemical messages (Hormones).
(nerve impulses)
Hormones travel through the
Impulses travel at high speed blood stream.
Generally brings about Generally brings about slow, long
fast, short term change term change
5. 1.The Nervous System
It is our interface to the outside world.
Is made up of 2 parts:
a) The Central Nervous System
(CNS) which is made up of the
Brain and Spinal Cord.
b) The Peripheral Nervous
System (PNS)
6. Neurons are the cells that carry
nerve signals around the body
All Neurons have the same basic
structures:
Dendrites: (from the Greek meaning
tree) branched extension of nerve
cells that receive nerve impulses from
other cells.
Cell Body (including a nucleus)
Axon: a long, slender projection that
conducts electrical impulses away
from the neuron's cell body.
NB: Neurons are some of the oldest and longest cells in
your body. You have many of the same neurons for
your whole life.
7. Axons & Dendrites

12. Is made up of 4 different types of
neurons; we will deal with 3 :
1. Brain Cells – These process
information.
2. Sensory Neurons – These
detect the outside world and send
signals to the CNS
3. Motor Neurons – These receive
signals from the CNS and pass
them on to muscles and glands.
13. Our Sensory Neurons receive or
detect information from specialised
cells.
This is then sent to the CNS for
processing. CNS
From the CNS commands are sent
to Motor Neurons in the PNS
which pass them on to muscles
and glands. Sensory
NB: Nerves only carry signals in one direction Neurons
Motor
Neurons
PNS
14. Synapses:
a small gap separating
neurons.
Signals travel through a
nerve as an electrical signal
but across synapse as a
chemical signal or
neurotransmitter.
15. Stimulus - Response
A Stimulus is any change in the environment of the
organism. The nervous system will then induce a
response, which may be movement, speech, blinking
etc.
Advanced organisms have specialised sense
organs, which are designed to detect stimuli.
These are often called receptors and are sensitive to one
stimuli (e.g. Skin to touch, eyes to light patterns)
A Response is how the organism reacts to the
stimulus and results in a change in behaviour
Examples
Stimulus: being cold - Response: move into the sun
Stimulus: Thirst - Response: Get a drink
16. The Reflex Arc
A reflex is the simplest form of response to a stimulus.
In a reflex reaction, the response occurs before the
message reaches the brain, or the message may not
reach the brain at all.
The receptor cell sends an impulse through a sensory
neuron to the spinal cord.
The message doesn’t go directly to the brain but to the
cell body of motor neuron and then to the muscle.
The muscle contracts and the response is issued.
The brain may get the message soon after. In reflexes,
the impulse is not related to stored information in the
brain before the response.
The most common reflex is the knee jerk.
17. Remember:
Information travels through the neurones as an
electrical impulse.
Nerve impulses travel in only one direction in a nerve
fibre. (Dendrites Axon)
Information is passed between neurones as chemical
messages.
