HUMAN BODY
BONES & MUSCLES
TOPICS

Bones.

The various types of joints & their
functions.

Various types of muscle movements in
man body.
SKELETON




The skeleton gives
definite shape to the body.
The skeleton helps in
locomotion.
The skeleton protects the
vital organs like the brain
and the heart.
An adult has 206 bones.
SKULL
The skull is the
skeleton of the head
The skull protects
the brain.
RIB CAGE

The rib-cage is a cage like
structure formed by
twelve pairs of ribs,
twelve thoracic vertebrae
and the sternum i.e. the
breast bone.

The rib-cage protects the
heart and the lungs.
VERTEBRAL COLUMN
(BACKBONE)



The vertebral column
forms the central axis of
the body.
The vertebral column
consists of 33 ring-like
bones called vertebrae.
The vertebral column
supports the head and
provides attachment to the
muscles of the back.
JOINT

The articulation or
attachment of two or more
bones is called a joint.

There are many types of
joints and their functions.
TYPES OF JOINTS

Hing joints are joints
which allow free
movements of the
articulating bones.

The easy movements of
bones.
BALL & SOCKET JOINT

The shoulder and hip joint
which move like a ball in
a cup are called ball and
socket joint.

Ball and socket joint
allows free movement of
arms and legs.
GLIDING JOINT

Gliding joint is a form of
freely movable joint in
which the bony surfaces
glide over each other.

For e.g. Joint in the
ankle/wrist.
PIVOT JOINT

The joint which facilitates
the rotatory movement is
called pivot joint.

The joint between the first
and second vertebrae is a
pivot joint.
MUSCLE

The muscle is a tissue
containing elongated cells
capable of contraction and
relaxation.

For e.g. Tongue, Heart.
Various types of muscle
movements in Human body


Voluntary Muscles : The
muscles whose actions are
under the control of the
will are called voluntary
muscles.
For e.g. Hands and Legs.
Involuntary Muscles : The
muscles whose actions are
not under the control of
the will are called
involuntary muscles.
For e.g. Heart beat, Blood
vessels, lungs.
What did you learn today?




A Person’s body is made up of large & small
bones. It gives the body shape & support. It also
protects the vital internal organs.
The bones are interlinked together in different
ways.
Human body has many muscles. Even they are
responsible for giving shape to the body.
Bone joints and muscles are responsible for the
movement.
