34. One Part of body Electrical impulses Another part

35.  Dendritic tip of a nerve receives electronic impulse from
muscular tissue present in sense organs

36.  This impulse travels from the dendrite to the cell body,
and then along the axon to its end.

37.  At the end, the electrical impulse gets converted into a
chemical signal for onward transmission.
Synapse

38.  A similar synapse finally allows delivery of such impulses
from neurons to other cells, such as muscles cells or gland

50.  ‘Reflex’ is a word we use
very commonly when we
talk about some sudden
action, which does not
involve thinking in
response to something in
the environment.

consciously about the
pain and the
possibility of getting
burnt, and therefore

57.  The process of detecting the
signal and responding to it
might be completed quickly,
known as reflex arc.

58.  Session is detected at that place only and responded very fast by
motor organs. Although the information input also goes to the
brain.This is the role of spinal cord.

60.  ‘Reflex’ is a word we use very commonly when we talk
about some sudden action in response to something in the
environment.
 Brain receives messages from sensory organs & gives
instruction to our motor organs to act accordingly
 Reflex arcs are formed in the spinal cord at the junction
between sensory and motor nerves

95.  Cerebrum receives sensory
impulses from various
receptors and interprets data
by putting together all
sensory impulses and stored
information in brain.
 A decision is made about how
to respond and the
information is passed on to
the motor areas which
control the movement of
voluntary muscles.

99.  The midbrain controls
many important functions
such as the visual and
auditory systems as well as
eye movement.

102.  Involuntary actions are
controlled by the medulla, like
BP, Heart beat.
 The pons connects the
medulla to the cerebellum
and helps coordinate
movement on each side of
the body.
 The Cerebellum is responsible
for precision of voluntary
actions and maintaining the
posture and balance of the
body.

109.  The fore-brain is the main thinking
part of the brain & controls voluntary actions.
 The mid-brain is the smallest part of brain & controls
many involuntary actions.
 The hindbrain is the structure that connects the spinal
cord to the brain control involuntary actions

122.  Muscle cells have special
proteins that change both
their shape and their
arrangement in the cell in
response to nervous electrical
impulses.
 When this happens, new
arrangements of these
proteins give the muscle cells
a shorter form.

123.  The brain is protected by Skull and Spinal cord is protected
by Back bone (Spine).
 Muscle cells will move by changing their shape when they
receive motor impulse send by brain.

134. “How does the plant detect
the touch, and how do the
leaves move in response?”

135.  But there is no nervous
tissue, nor any muscle tissue
in plants for the conduction
of information.

136.  Plant cells change shape by
changing the amount of water
in them, resulting in swelling or
shrinking, and therefore in
changing shapes.

138.  Plants show two different types of movement
1. Independent of growth.
2. Dependent on growth
 Sensitive plants actually move its leaves in response to touch
 The plants also use electrical-chemical means to convey this
information from cell to cell
 Some cells must change shape in order for movement to happen.

154.  Normally plants respond to stimuli slowly by growing in a particular
direction, so plants growth is directional

transmission must be able to
move rapidly.

160.  Presence of nerves is
compulsory.
 Cells cannot continually
create and transmit
electrical impulses.

161. In case of plants

movement of ions

165.  Stimulated cells release a
chemical compound, this
compound would diffuse
all around the original cell.
 Other cells would be able
detect these and recognize
information, and even
transmit it.

166.  Electrical impulse helps to give fast response
in case of animals
 Electrical-chemical impulse helps to give fast response in
case of sensitive plants

 Diffuses towards the shady
side of the shoot.
 Stimulates the cells to grow
longer.
 Plants grow towards light.

180. Cytokinins
 They are present in greater
concentration in areas of
rapid cell division, such as
in fruits and seeds.

181. Ethylene  It is a gaseous hormone
H2C=CH2

182. Gibberellins
 Also stimulates cell division
and elongation.

183. Abscisic acid  Its effects include
wilting of leaves.

196.  When a person becomes angry
Adrenaline adrenaline is secreted into the
blood. It helps the body to adjust
to sudden stress. As a result,
 Adrenaline causes the heart to
beat faster, result in supply of O2
to the body muscles increases.
 Small arteries constrict which
increases the blood pressure.
This diverts the blood to our
skeletal muscles.

198.  One of the symptoms in
this disease is a swollen
neck.

199.  Iodine is essential for the

carbohydrate, protein and fat
metabolism in the body so as
to provide the best balance for
growth.

are because of the

in males and oestrogen in
females.

210.  Helps in regulating blood
sugar levels.
 If it is not secreted in
proper amounts, the
sugar level in the blood
rises causing many
harmful effects.
