This document discusses the physiological foundations of human behavior. It begins by stating that human behavior is influenced by many physiological and psychological factors. It then provides an overview of the nervous system, including the central nervous system (brain and spinal cord) and peripheral nervous system. Within the central nervous system, it describes the main parts of the brain (hindbrain, midbrain, forebrain) and spinal cord. It also discusses neurons, nerves, and the classifications and functions of different types of neurons. The document concludes by covering the peripheral and autonomic nervous systems, and describing the main endocrine glands in the body.
Psychobiologist study the evolutionary and physiological mechanisms that are responsible for human behavior and try to understand how the brain functions in order to understand why humans behave the way we do.

Unit – 11:
Types of nerves- structure and functions
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)
Deep structure of Brain:
Hypothalamus: is located in the floor of the third ventricle and
It talks about nervous system and brain behavior. This include discussion about brain, different aspects of human behavior and thought such us cental core, limbic system and cerebral cortex. Also, it discusses what consists od central core (brainstem, thalamus and cerebellum).
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.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

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.

3. THE NERVOUS SYSTEM
The most complex and elaborate
system of structures in the human body
Composed of a group of interrelated
and interrelating units that enable man
to receive stimuli from the environment
and to make the necessary and
appropriate responses to such stimuli
Regulates the behaviour of the whole
individual to enable him to survive
4. THE NERVOUS SYSTEM
PERIPHERAL
NERVOUS SYTEM
Part of the nervous
system outside the
brain and the spinal
cord which includes
all the nerves
CENTRAL
NERVOUS SYSTEM
Composed of the
brain and the spinal
cord
5. Central Nervous System
SPINAL CORD
Composed mainly of the nerve
connections running between
the brain and the various parts of
the body
There are 31 pairs of spinal
nerves
These nerves are mixed nerves
with both motor and sensory
fibers
Each nerve is attached to the
cord by two roots:
1. Dorsal root
Transmits sensory impulses
2.Ventral root
Transmits motor impulses
BRAIN
Portion of the nervous
system that is encased
in the cranial bones
Weighs 3 lbs and
contains 90 % of the
body’s neurons
The most specialized
organ in the body
7. • Situated at the back of and above the medulla
• Composed of hemisphere
• Controls body balance and keeps us right side up
• Assists in coordinating our bodily movements and keeping
them rhythmic and accurate
• Plays an important role in controlling the tonicity of the
skeletal muscles
Cerebellum
• Contains nerve fibers that connects both hemispheres of the
cerebellum with each other as well as with nerve fibers that
transmit neural impulses upward and downward within the
central nervous system
• Portion of the brain with an enlarge ventral portion above the
medulla
PonsVaroli
• The lowest portion of the brain and it connects with the spinal
cord
• Nervous impulses travel through it to and from the higher brain
centers
• It contains centers that regulate heart beat, blood pressure and
breathing and it controls the activities of the internal organs
Medulla
Oblongata
8. • Brain’s major relay station connecting the lower structure of
the brain and the spinal cord with the cerebrum
• Here lies the cell bodies of important connecting neurons for
the various senses
• These neurons receive messages from the sense organs and
send them to specific centers in the cerebrum
Thalamus
• IncludesAmygdala, Hippocampus, Siptum, and portions of the
Hypothalamus andThalamus
• It performs many functions specially receiving sensory messages from the
visceral organs and helps control their activities
• AMYGDALA-connected with Hypothalamus serves as the main area
involved with emotions and fundamental for self-preservation, when
triggered, it gives rise to fear and anxiety which leads animal to a stage of
alertness
• HIPPOCAMPUS-involved with memory, especially the formation of long-
term memory
Limbic
System
• The largest part of the brain
• Divided into two halves called the Cerebral Hemispheres
• These hemispheres contains centers for sensory integration and
for voluntary motor activity activities
• Also play important roles in governing memory and intelligence
Cerebrum
9. THE NEURON
The basic unit of nervous system also known
as nerve cell
About 100 billion of it in the brain of an
average size
variety of shape and sizes but all possess
common attributes
Each of it is composed of a cell body which
contains a nucleus
10. NERVE
A compound structure consisting of a number
of neuron fibers bound together
There may be thousands of fibers in a single
nerve
Each of these neuron fibers is insulated from
all the others and conduct impulses
independently of the others
11. CLASSIFICATION OF
NEURONS
ACCORDING TO THEIR FUNCTION
AFFERENT or Sensory Neurons
Carry messages towards the central nervous system
from the receptors such as the eyes, ears, and other
sense organs
EFFERENT or Motor Neurons
Carry messages from the central nervous system to
the muscles and glands
CONNECTING or Association Neurons
Also called as middle me between neurons
Between the sensory and motor neurons
Most of it found within the central nervous system
12. THE PERIPHERAL NERVOUS SYSTEM
COMPOSED OF NERVESTHAT CONNECTSTHE BRAINANDTHE SPINAL
CORDTOTHE PERIPHERYOFTHE BODY
• Are found outside the central nervous system
• They connect to the skin, muscles and glands
Peripheral
Nerves
• Nerves carrying sensory input to the central
nervous system
Afferent
nerves
• Carrying motor output away from the central
nervous system to muscles and glands
Efferent
nerves
13. THE AUTONOMIC NERVOUS SYSTEM
BEYOND OURVOLUNTARY CONTROL AND IT
CONTROLS HEART ACTION, DIGESTION,
EXCRETION, SALIVATION, AS WELL ASTHOSE
INVOLVED WITH SEXUAL ORGASM,
PERSPIRATION
DIVIDED INTO :
SYMPATHETIC
Tends to operate in stress situations
Example: it increases heart beat when danger threatens
PARASYMPATHETIC
Governs regular activities
Example: it slows down the heart for normal functioning
14. THE ENDOCRINE GLANDS
1. PITUITARY GLANDS
Sometimes called the master glands
2. THYROID GLANDS
Located in the neck and produce the hormone Thyroxin
3. PARATHYROID GLANDS
Secret Parathormone, a hormone necessary to control balance of
various minerals in the bloodstream especially calcium
4. THYMUS
Sometimes called the Gland of Childhood
5. ADRENALS
Composed of two part: the Medulla (inner part) secretes Adrenalin,
and the Cortex (outer part). Adrenalin is referred to as the
emergency hormone because it enables one to cope with
emergency situations
6. ISLETS OF LANGERHANS
Group of cells in the Pancreas which secrets Insulin that is needed in
the regulation of blood sugar by the cells
7. GONADS
1. Refer to the Ovaries (produce Estrogens and Progesterone) and
Testes ( produce male sex hormone Testosterone)
