Identify the bones respectively

Long Bones

longer than they are wide

Short bones

can be approximately cube-shaped

Short bones

length is similar to width/depth/diameter

Flat bones

have a thin shape, in some case. it provides mechanical protection to soft tissues beneath or enclosed by flat bone

Irregular bones

have complicated shape that cannot be classified as long, short, or flat

Irregular bones

Their shape depends with their role

Sesamoid bones

Develop in some tendons in locations where there is considerable frictions, tension, and physical stress

Skeletal system

It provides supporting frameworks of body

Skeletal system

It provides lever for muscle

calcium and phosphorus

Skeletal system has minerals like ?

Ossification or osteogenesis

It is the process of bone formation by osteoblast

Intramembranous ossification

fibrous membranes of some part of fetal skeleton are converted to bone

Endochondral ossification

conversion of cartilage into bone. All of the bones of the body, except for the flat bones of the skull, mandible, and clavicles, are formed through ?

Joints

this provide the means for movement

Joints

also known as an articulation or articular surface

Joints

a connection that occurs between bones in the skeletal system

fibrous joints

these are fixed joints

immovable joints

fibrous joints are also called ?

fibrous joints

these are found where bones are not flexible

Cartilaginous joints

These joints occur only in those regions where the connection between the articulating bones is made up of cartilage.

Synovial joints

the most common type of joint

Synovial joints

this joint helps us to perform a wide range of motion such as walking, running, typing and more

Pivotal Joints

In this type of joint, one bone has tapped into the other in such a way that full rotation is not possible.

Pivotal Joints

This joint aid in sideways and back-forth movement

Hinge Joints

only back and forth movement is possible

Saddle joints

the biaxial joint

Saddle joints

allows the movement on two planes– flexion/extension and abduction/adduction.

Plane joints/Gliding

This joint permit two or more round or flat bones to move freely together without any rubbing or crushing of bones.

Ball and Socket Joints

One bone is hooked into the hollow space of another bone

Ball and Socket Joints

This type of joint helps in rotatory movement.

Condyloid joints

the joints with two axes which permit up-down and side-toside motions

Condylar or ellipsoid joints

Condyloid joints are also known as ?

Pivotal Joints

What type of joint is neck

Hinge joints

What type of joint is ankle

Hinge joints

What type of joint is elbows

Hinge joints

What type of joint is knee joints

Saddle joints

What type of joint is thumb

Plane joints/Gliding

What type of joint is lower leg to ankle joint

Plane joints/Gliding

What type of joint is forearm to wrist joint

Ball and Socket Joints

What type of joint is shoulders

Condyloid Joints

What type of joint is the base of the finger

Condyloid Joints

What type of joint is carpals of the wrist

Condyloid Joints

What type of joint is the wrist joints

Skeletal system

provides support, movement, protection, blood cell production, and mineral storage.

How many thoracic vertebrae are there

5

How many lumbar vertebrae are there

Axial Skeleton

This forms the core structure of the body

Skull

Protects the brain

Vertebral Column

Supports the body and protects the spinal cord

Ribs

Protects the heart and lungs

Appendicular Skeleton

This consists of the limbs and girdles, allowing movement.

Pectoral Girdle

Connects the upper limbs to the axial skeleton

Pectoral Girdle

Allows a wide range of arm movement

Pelvic Girdle

Supports the weight of the upper body

Pelvic Girdle

Protects the reproductive and urinary organs
