 Bone is one-third connective tissue.
 It is impregnated with calcium salt.
Bones give shape and support to the body,
and resist any forms of stress.
 Provides attachment of muscles, tendons,
ligaments.
 The skull, vertebral column and thoracic
cage protect brain, spinal cord and thoracic
and some abdominal viscera, respectively.
 Bone marrow manufactures blood cells.
 Bone marrow contains reticulo endothelial cell
which are phagocytic…
 Bone stores 97% of the body calcium and
phosphorus.
 According to shape
 Developmental bones
 Regional classification
 Structural classification
ACCORDING TO
SHAPE:-
 LONG BONES: Each
long bone has an
elongated shaft
(diaphysis) and two
expanded
ends(epiphysis).
Eg.humerus, femur
 SHORT BONES: There shape is usually
cuboid, or scaphoid. E.g. tarsal and carpal
bones
 FLAT BONES: Resemble shallow plates and form
boundaries of certain body cavities.eg-bones in vault of
the skull, sternum, ribs and scapula.
 IRREGULAR BONES: Bones that is irregular in
structure. E.g.- hip bone and bones in the base of
the skull or sphenoid and first and second
cervical vertebrae.
 SESAMOID BONES: These are bony nodules
found embedded in the tendons or joint
capsules.
 Generally not present in our body.
 Formed due to non fusion of epiphysis.
 Appearance of extra ossification centres .
 Axial skeleton
 Appendicular skeleton
 Includes skull,
vertebral column and
thoracic cage.
 Includes bones of the limbs e.g pectoral
girdle, free upper limb and pelvic girdle,
free lower limb.

JOINTS
 Joint is a junction between two or more
bones or cartilage. It is a device to permit
movements.
 CHARACTERSTICS OF
JOINTS
 Articular surfaces are
covered with
hyaline(articular) cartilage.
 Between the articular
surfaces there is a joint
cavity filled with synovial
fluid.
 Joint is surrounded by
fibrous joint capsule lined
by synovial membrane.

FIBROUS JOINTS
 Bones are joined by fibrous tissue.
 Joints are either immovable or permit a slight
degree of movement.
 These can be grouped in the following three
subtypes.
 Sutures
 Syndesmosis
 Gomphosis
Sutures:
 Immovable
 Found in skull
Syndesmosis:-
 The bones are connected by the interosseous
ligament. E.g.inferior tibiofibularjoint.
Gomphosis(peg and socket joint
 e.g. root of the tooth in its bony
socket.
CARTILAGINOUS
JOINTS:
CARTILAGINOUS JOINTS:
 In this type of joints the bones are joined by
cartilage.
 These are of the following two types:
 Primary cartilaginous joints (synchondrosis, or
hyaline cartilage joints.
 Secondary cartilaginous joints(Symphyses or
fibrocartilaginous joints):
Primary cartilaginous joints
(synchondrosis, or hyaline cartilage
joints):
 Bones are united by a plate of hyaline
cartilage so that the joint is immovable
and strong.
 e.g. Joint between epiphysis and
diaphysis of a growing long bone,
Sternocoastal joint
Secondarycartilaginous
joints(Symphyses or fibrocartilaginous
joints):
 Articular surfaces are covered by a thin layer of
hyaline cartilage and united by a disc of
fibrocartilage.
 Permanent and persist throughout life.
E.g.symphysis pubis, interverterbral joints.
SYNOVIAL JOINTS
 Synovial joints are most evolved, and
therefore, most mobile type of joints.
Classification of synovial joints and their
movements:-
 PLANE SYNOVIAL JOINTS:
 Articular surfaces are more or less flat (plane)
 Permit gliding movements (translations) in various
directions
 E.g.Intercarpal joints, Intertarsal joints.
 HINGE JOINT:
 Articular surfaces are pulley- shaped.
 There are strong collateral ligaments.
 Movements are permitted in one plane around
a transverse axis.
 Allows flexion and extension
 .E.g.elbow joint, Ankle joint
 PIVOT (TROCHOID) JOINTS:
 Articular surfaces comprise a central bony
pivot (peg) surrounded by an
osteoligamentous ring.
 Movements are permitted in one plane around
a vertical axis.
 Allows pronation and supination
 E.g. Superior and inferior radio of ulnar joints
 BALL AND SOCKET(SPHEROIDAL) JOINTS:
 Articular surfaces include a globular head
(male surface) fitting into a cup shaped
socket(female surface).
 Movements occur around an indefinite
number of axes which have common center.
 Flexion, extension, abduction, adduction,
medial rotation, lateral rotation, and
circumduction all occur quite freely. E.g.
Shoulder joint, Hip joint.
 ELLIPSOID JOINTS:
 Articular surfaces include an oval, convex, male
surface fitting into an elliptical, concave female
surface.
 Free movements are permitted around both the
axis, flexion and extension around the transverse
axis, and abduction and adduction .
 E.g.wrist joint,
 SADDLE JOINTS:
 Articular surfaces are reciprocally concave.
 Movements are similar to those permitted by
and ellipsoid joint, with addition of some
rotation(conjunct rotation) .
 E.g.carpometacarpal joint of the thumb
FUNCTIONAL
CLASSIFICATION (ACCORDING
TO THE DEGREE OF
MOBILITY)
 Fixed or immovable
joints
 Articular surfaces are
joined by tough
fibrous tissue
 e.g sutures of the
skull.
 Slight movement is
possible.
 A pad of cartilage lies
between the bones
surfaces, and there are
fibrous ligaments to hold
the bones surfaces,.
e.g. the intervertebral
discs between the bodies
of the vertebrae
 Freely moveable joints
 The ligaments are of elastic connective tissue.
 Eg .all synovial joints
REGIONAL
CLASSIFICATION
Skull type
 Immovable
Vertebral type
 Slightly movable
Limb type
 Freely movable.
ACCORDING TO NUMBER
OF ARTICULATING
BONES:-
 Only two bones takes part in formation of joints,
e.g. interphalangeal joints.
 More than two bones take parts in the formation of
joints. e.g. elbow joint, wrist joint.
when joint cavity is divided into two by an
intra-articular disc eg.Tempromandibular joint
and sternoclavicular joint.
MUSCLES
 Muscles are group of specialised contractile
cells, also called “FIBRES”. Its function is to
produce force and cause motion, either
locomotion or movement within internal
organs
 Skeletal muscle
 Cardiac muscle
 Smooth muscle
 LOCATION:-Usually attached to the bones of
the skeleton.e.g muscles of limb
 CHARACTERISTICS:-
 Attached by tendons to bones.
 Multinucleated
 Striated- have stripes, banding.
 Voluntary movement of skeletal parts.
 FUNCTION:
 Movement of the
skeleton
eg. movement of
limbs, fingers, toes,
neck, etc.
 Movement of
tissues of facial
expression. e.g.
ability to smile and
to frown.
 LOCATION:- Found mainly in the walls of
hollow organs, vessels, respiratory pathway.
 Function:
 Digestive system- to move food along the
gastrointestinal tract .
 Regulating the diameter of blood vessels and parts
of respiratory tract.
 LOCATION:-Found only in the heart
 CHARACTERISTICS:-
 Striations
 Branching cells
 Involuntary muscles
 Usually has a single nucleus, but can have
more than one.
 Function:
 Pumping of blood through the heart:
Alternate contraction and relaxation of
cardiac muscle.
 Muscle fibers
 Epimysium
 Fascicles
 Perimysium
 Endomysium.
 Tendon

 Muscles are the organs that move body parts.
Your muscular system does lots of important
jobs. It helps you move, pumps your blood,
helps you digest food and even helps you
breathe.
