This document summarizes coordination and control in the human body. It discusses how the nervous system and endocrine system work together to coordinate the body's activities. The nervous system uses neurons, nerve impulses, and reflex arcs to transmit signals rapidly. The endocrine system releases hormones that travel via the bloodstream to regulate functions like growth, metabolism, and stress response. Key glands discussed include the hypothalamus, pituitary, thyroid, adrenals, and reproductive organs, along with the hormones they secrete to maintain homeostasis.

How Do Organisms Reproduce ? - Class 10 CBSE science (BIo)Amit Choube
Reproduction is an integral feature of all living beings. The process by which a living being produces its own like is called reproduction.
Importance of Reproduction:
Reproduction is important for each species, because this is the only way for a living being to continue its lineage. Apart from being important for a particular individual, reproduction is also important for the whole ecosystem. Reproduction helps in maintaining a proper balance among various biotic constituents of the ecosystem. Moreover, reproduction also facilitates evolution because variations come through reproduction; over several generations.

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

An overview of cerebrovascular disorders is given in this file, which includes ailments including aneurysms, strokes, and vascular abnormalities that affect the blood arteries in the brain. With a focus on causes, symptoms, diagnosis techniques, and treatment options, it provides a thorough overview of these important neurological diseases.
Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
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.

In addition to offering my frank assessment of Success Insider’s LMA Course, this piece examines the course’s effects via a variety of Tim Han LMA course reviews and Success Insider comments.
2. • “ It is the type of coordination present
between the cells or different organs
within the body of multicellular
organisms. In this kind of coordination
a group of cells releases specific
chemicals, which regulates the activities
of other cell of the body.”
3. In animals Nervous
system & Hormonal
system plays an
important role in
control & co-
ordination.
In plants control and
coordination is done by
chemical substances
called plant hormones
or phytohormones.
4. • Coordination in animals :- In animals control and
co ordination is done by the Nervous system and
Endocrine system.
• Nervous system- The nervous system is an organ
system containing a network of specialized cells
called neurons.
• Types of Nervous system-
• 1.Central Nervous system(CNS) – It includes –
Brain & Spinal cord.
• 2.Peripheral Nervous system( PNS)- It includes a.
Somatic nervous system(SNS)- it is also known as
voluntary nervous system & associated with the
voluntary control of body movements via skeletal
muscles.
6. Structure of Neurons
• It has a cell body called cyton containing a
nucleus and cytoplasm. It has several
branched structures called dendrites. It has a
long nerve fiber called axon which may
covered by Schwann cells & a protective
covering called Myelin sheath. Schwann cells
separated by a gap called as Nodes of Ranvier.
Neuron ends by bulb like structure at nerve
ending called as Synaptic Knob.
8. Nerve Impulse
• Nerve impulse -Messages
pass through the nerve
cell in the form of
chemical and electrical
signals called nerve
impulse. The dendrites
receive the information
and starts a chemical
reaction which produce
electrical impulse which
passes through the axon.
9. Reflex Action
• Reflex action Reflex action is a sudden,
unconscious and involuntary response of the
effectors to a stimulus.
• Ex :- We suddenly withdraw our hand if we
suddenly touch a hot object. In this reflex action,
the nerves in the skin (receptor) detects the heat
and passes the message through the sensory
nerves to the spinal cord. Then the information
passes through the motor nerves to the muscles
(effectors) of the hand and we withdraw our
hand.
10. Reflex Arc
• REFLEX ARC- The pathway
of a reflex action is called
reflex arc. In a reflex arc the
stimulus is received by the
receptors (sense organs)
and it passes through the
sensory nerves to the spinal
cord. From the spinal cord
the information passes
through the motor nerves
to the effectors
(muscles/glands) for the
response.
11. Role of Brain
• The brain plays no action as the reflex action
takes place at the level of spinal cord. But later
brain is informed by the spinal cord and then
later the thinking part of the action is done by
brain. But brain is not active during A reflex
action. Difference between Reflex action &
walking. Reflex action 1. It is inborn, involuntary (
automatic) & require for survival & protection.
Walking- 1.It is acquire by learning, under control
of brain(voluntary) & for various function
13. Human Brain
• The brain is the main coordinating centre in the human body. It is
protected by the cranium. It is covered by three membranes called
meninges filled with a fluid called cerebrospinal fluid which protects
the brain from shocks. The brain has three main parts. They are fore
brain, mid brain and hind brain.
• i) Fore brain consists of the cerebrum and Thalamus. It is the
thinking part of the brain and controls voluntary actions. It controls
touch, smell, hearing, taste, sight, mental activities like thinking,
learning, memory, emotions etc.
• ii) Mid brain controls involuntary actions and reflex movements
of head, neck, eyes etc.
• iii) Hind brain consists of cerebellum, pons and medulla.
Cerebellum controls body movements, balance and posture. Pons
controls respiration. Medulla controls heart beat, blood pressure,
swallowing, coughing, sneezing, vomitting etc.
14. Spinal Cord
• Spinal cord The
spinal cord starts from
the brain and extends
through the vertebral
column. It has 31 pairs
of spinal nerves. It
carries messages to
and from the brain. It
also controls reflex
actions.
15. Muscles are 3 types
• Skeletal muscles (Voluntary muscles /Striated muscles)-
attached with bones & having alternate dark and light
bands.
• Smooth muscles (Involuntary muscles /Non striated
muscles) present in internal body organs.
• Cardiac muscles- present in heart Nerve impulse
reaches to muscle which resulted into muscular action.
17. Endocrine Glands
• Endocrine glands in human beings The
endocrine glands are also known as Ductless
gland. The endocrine glands produce chemical
substances called as Hormones, and it directly
diffuses into blood and reaches to target organ.
• The endocrine glands in our body are pineal,
hypothalamus, pituitary, thyroid, parathyroid,
thymus, pancreas, adrenal, testes and ovary.
18. Glands In our Body
• Hypothalamus gland –it forms various
releasing or inhibiting hormones & regulate
the Pituitory glands for further function.
• Pituitory gland- It function in response of
hypothalamus & releases hormones. For ex.
GH-Growth hormones – It help for body
growth.
20. Glands In our Body
• Thyroid glands- a pair of glands present in neck region, which forms
thyroxin hormone in response of TSH of pituitory.
• Thyroxin hormone - Thyroxin controls the metabolism of
carbohydrates, fats and proteins and helps in proper growth. If the
diet is deficient in iodine it causes deficiency of thyroxin leads to
cause the goiter in which enlargement of thyroid glands cause the
swelling of neck. The goiter disease are generally found in people
living in northern sub-himalayan areas where the diet are deficient
of iodine. Hence one must take the iodized salt. Excess secretion of
thyroxin cause exophthalmia (protrusion of eyes)
• Parathyroid glands- two pair of parathyroid glands which are close
to thyroid gland. It secretes the parathormone which require to
control the Calcium and phosphorous. It deficiency cause Cramps
and spasms Thymus gland- It is present near the heart & secretes
the hormone Thymosine. It is required for maturation of T-
lymphocytes which require for immunity.
22. Glands In our Body
• Adrenal glands –> a pair of glands present over the Kidney, Adrenal
gland have two parts-
• Outer Adrenal cortex
• inner medulla.
• Adrenal cortex - stimulated by ACTH & forms 3 hormones namely -
Gluco-corticoids, Mineralo-corticoids, Androgens. . It requires for
Glucose metabolism, mineral balance, secondary sexual characters
respectively.
• Adrenal medulla- it produces two hormones – Adrenaline & Nor
adrenaline hormone – It is also known as Emergency hormone or
hormone of 3 F – Fight,Flight,Freight. It increase of heart beats,
blood pressure, rate of breathing , causes rapid contraction of rib
muscles etc to full fill the increasing demand of body. Nor
adrenaline hormone- It require for normal functioning of heart
beat, blood pressure, breathing rate etc.
