Choose the correct statement(s) referring to the skeletal system:

It includes all the organs in the body (solid and resistant organs), It includes all the bones of the body and their connecting joints, It is a system of organs which support locomotion and movement

Choose the correct statement(s) referring to bones and joints:

The skeleton is made up of bones connected to each other by joints, Long bones consist of epiphysis and diaphysis, The skeleton supports the body and facilitates locomotion

Choose the correct statement(s) referring to the location of bones:

The axial skeleton consists of the thoracic cavity (rib cage), the spinal column and the bones of the head, The skeleton of the limbs includes the corresponding girdles which connect the limb to the axial skeleton, The pectoral girdle connects the upper limb to the trunk

According to their shape, bones can be:

Long bones, such as the femur, the humerus and the tibia, Flat bones, such as the scapula, the sternum and the cranial bones, Short bones, such as the carpal and the tarsal bones

The following bones are short bones:

The bones of the wrist (carpal bones), The bones of the tarsus (tarsal bones)

Choose the correct statement(s) referring to the bone system:

Blood cells are formed in the red bone marrow from the spongy bones, Collagen makes bones flexible, while hydroxyapatite makes them hard, The medullary cavity represents the bone’s central cavity

Choose the correct statement(s) referring to the function of bones:

Movement is carried out together with the skeletal muscles, Their support function provides support to the body, They ensure protection for vital organs (lungs)

The following statement(s) is/are true referring to the red bone marrow:

It has a role in haematopoiesis, It can be found in the spongy bones, It has a role in the production of red blood cells, leukocytes and platelets

Irregular bones include:

The patellae and wormian bones, The vertebrae

Select the flat bones from below:

Some of the cranial bones (the parietal), The pelvic bones, The scapula (the shoulder blade)

Choose the correct statement(s) about bones:

Long bones have a diaphysis delimited at each end by an epiphysis, Wormian bones are the irregular bones of the cranial sutures, Cranial bones, the bones of the vertebral column and of the thoracic cavity form together the axial skeleton

The compact bone tissue:

Is a component of the diaphysis of long bones

According to shape, bones can be classified into:

Flat bones (shoulder blades), Irregular bones (sesamoid), Short bones (tarsals)

It is true that long bones:

Belong to the skeleton of the limbs, Have a diaphysis or shaft, Have two epiphyses and a diaphysis

The following statement(s) is/are true about the bone tissue:

In order to carry out their functions, bones must be hard and rigid, Bone flexibility is the ability of a bone to bend to a certain degree, Short bones include the tarsals and carpals

Choose the false statement(s) from below:

The axial skeleton includes all the bones of the body with the exception of the long bones of the limbs, The bones of the tarsus belong to the lower limb, The vertebrae belong to the flat bones

Choose the correct associations between the shape of the bone and its location in the skeleton:

Vertebra – irregular bone – vertebral column, Patella – knee joint – irregular sesamoid bone

Choose the correct statement(s) referring to the functions of the bones in the body:

Protection – the bones of the skull protect the delicate tissues of the encephalon, Protection – the sternum together with the ribs contribute to the protection of certain organs in the thorax, Support – bones serve as points for the attachment of skeletal muscles

Choose the correct statement(s) from below:

The red bone marrow is the site where blood cells are created, The diaphysis and epiphysis are not components of the scapula and of the vertebrae, The periosteum covers the diaphysis of long bones

Choose the true statement(s) referring to the periosteum

It is a connective tissue which partially covers a long bone, The periosteum is absent from the articular surfaces of a long bone, It covers the long, straight part of certain bones such as the femur or the humerus

Which elements are part of the histological structure of the long human bone?

Compact bone, spongy bone, endosteum, periosteum, A diaphysis, two epiphyses, two metaphyses, Spongy bone in the epiphyses, compact bone in the diaphyses, articular cartilage at the epiphyseal extremities

The diaphysis and the epiphysis are components of:

Humerus, femur, ulna

Choose the correct statement(s) referring to the histological structure of the bone:

The compact bone has concentric rings organised in systems called osteons, The osteon has perforating canals which connect the central canals to the bone canals, The concentric bone lamellae contain lacunae which contain osteocytes

Choose the correct statement(s) referring to the histological structure of the bone:

The osteon has a central canal which contains nerves and blood capillaries, The haversian system is a characteristic of the compact bone

The following is true about the osteon:

The osteon’s central canal contains blood vessels (blood capillaries) and nerves, It contains concentric rings (bone lamellae) surrounding each central canal, It is separated from neighbouring osteons by areas containing interstitial lamellae
