are provided by some form of skeleton. Hydrostatic
skeleton Exoskeleton endoskeleton
HYDROSTATIC SKELETON
A fluid-filled internal body cavity in which the fluid is held under pressure maintaining the body shape & providing for internal organ
The cavity is surrounded by muscles arranged in layers.
The body shape of the animal changes as these muscles contract &
The animals are soft & flexible, the hydrostatic fluid does protect body parts by acting as a shock absorber. Examples : earthworm, jellyfish, leech & caterpillar.
EXOSKELETON
A rigid outer covering usually made up of protein, chitins &/@ calcium salt.
Insects – the cuticle (covered with wax to prevent water loss from the body), cover the body’s surface.
The exoskeleton is ted / hinged = certain points of the skeleton are flexible & can bend enabling the
Exoskeleton restrict the growth of animals the exoskeleton must be shed from time to time in order for the animal to grow. (ecdysis)
Also found in the shells of molluscs & the bony plates of tortoises.
Examples : insects, crabs, lobsters, tortoise
ENDOSKELETON
Found in the bodies of all vertebrates including fish, amphibians & birds.
Consist of hard skeleton of bones & cartilage found inside the body – made up of calcium & phosphate.
Works with the muscular system to perform movement & locomotion. It the body & protects the organs.
The Necessity for & Locomotion in Humans & Animals
The functions of skeleton : Provide
shape & Enables movement (locomotion) Protects internal organs Stores calcium & phosphate ions Produces blood cells A firm base for the attachment of muscles
The Necessity for & Locomotion in Humans & Animals
Problems that could be faced by humans and animals in and locomotion, gravitational
force, friction & resistance when moving around
Aspect need to be considered when describing the locomotion of an animal :Stability – when it moves, it is temporarily unstable, but its stability will be restored when it stops. – must have enough from
HOW TO OVERCOME THE PROBLEMS?
RESISTANCE & FRICTION – by streamlining their bodies.
GRAVITATIONAL FORCE – most animals have their own ing structures (fins – fishes, wings – birds & strong limbs – tetrapods & humans) provide the propulsive force to overcome the problem
The skeletal system together with its muscles are designed specially to overcome the problems associated with & locomotion of humans & animals.
To initiate locomotion, the force required is generated by contraction of muscles, whereas
THE HUMAN SKELETAL SYSTEM
The adult human skeleton consist of 206 bones.
Divided into two main parts : the axial skeleton & the appendicular skeleton.
The axial skeleton : made up of the bones that form the vertical axis of the body.
The appendicular skeleton : made up of the bones that are attached to the axial skeleton.
Include bones of the limbs, the pectoral girdle & the pelvic girdle.
FUNCTION OF THE SKELETON
PROTECTION – the skull protects the brain, the vertebral column protects the spinal cord & the rib cage protects internal organs such as the heart.
– act as a framework to the soft body parts, to maintain the upright position & to keep the body stable.
FUNCTION OF THE SKELETON
MOVEMENT – bones interact with the skeletal muscle.
BLOOD CELL FORMATION – most of the blood cells are formed in the bone marrow of the long bones.
MINERAL STORAGE – bones act as a reservoir for calcium & phosphorus.

VERTEBRAL COLUMN
Known as the spine/ backbone.
Extends from the base of the skull to the pelvic girdle.
Made up of 33 vertebrae separated from each other by discs of cartilage (intervertebral discs) which absorb shocks & serve as flex point.
This S-shaped column s & balances the body in a vertical plane & protects the spinal cord, s the skull & provides a base for the attachment of muscles to the back.
VERTEBRAL COLUMN
The vertebrae differ in structure & function in different regions of the vertebral column.
A vertebra typically consists of a main body (the centrum), a neural arch & transverse processes.

THE STERNUM & RIBS
The rib cage consists of 12 pairs of ribs with the thoracic vertebrae at the back portion of the body & to the sternum in the front portion. Movement of the rib cage are brought about by intercostal muscles between the ribs.
THE STERNUM & RIBS
The sternum & ribs enclose & protect the internal organs (the lungs & heart) & play an important role in breathing.
PECTORAL GIRDLE

FORELIMB BONES
Consists of humerus, radius & ulna. The Humerus :
The long bones of the upper arm Rounded head end fits into an open socket of the scapula forming a ball-and-socket t (allow movement in all planes)
The posterior end of the humerus forms a hinge t with the ulna with the ulnaradius bones, allowing movement in one plane only. The radius & ulna :
The bones on the forearm in which the ulna is longer than the radius. It has a notch at its upper end which articulates the humerus at the elbow.
