  2. Shoulder

  3. Elbow

  4. Skull
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Our body is made up of many joints. Each of these joints is of different categories and perform specific functions. They may be movable joints or immovable joints. Among the movable joints, some are hinge joints. This means that they are able to move about one axis. They are a type of synovial joint.

So the correct option is C.

The branch of study dealing with joints is

  1. Osteology

  2. Chondrology

  3. Craniology

  4. Arthrology
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Osteology is the study of the structure and function of the skeleton and bony structures.

Chondrology is the branch of anatomy that deals with cartilage.
Craniology is the scientific study of the shape and size of the skulls of different human races.
Arthrology is the science concerned with the study of anatomy, function, dysfunction and treatment of joints and articulations.
Hence, Arthrology is the branch of science dealing with the study of joints.

Choose the wrong match with reference to joints.

  1. Gomposes $\rightarrow$ Intercarpal joints
  2. Syndesmoses $\rightarrow$ Joint between tibia and fibula
  3. Symphysis $\rightarrow$ Joint between vertebrae
  4. Synchondrosis $\rightarrow$ Epiphyseal plate
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • A joint is a location at which two or more bones make contact.
  • Fibrous or immovable joints are connected by dense connective tissue, consisting mainly of collagen.
  • Gomposes is a type of fibrous joint. It is a joint between the root of a tooth and the sockets in the maxilla or mandible.
  • So, the correct answer is 'Gomposes →→ Intercarpal joints'

Identify the correct statement.

  1. Joint between adjacent vertebrae is a fibrous joint.

  2. Decreased level of progesterone causes osteoporosis in old people.

  3. Accumulation of uric acid crystals in joints causes their inflammation.

  4. Vertebral column has 10 thoracic vertebrae.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Gout is a metabolic disease in which crystals of uric acid gets deposited in joints, tendons and surrounding soft tissues.
  • Symptoms of gout increase irritation, inflammation of joints and tendon tissue, joints become hot red and swollen.
  • Hence accumulation of uric acid crystals in joints causes their inflammation.
  • So, the correct answer is 'Accumulation of uric acid crystals in joints causes their inflammation'.

Select the correct match.

  1. Pivot joint $\rightarrow$ Between third and fourth cervical vertebrae
  2. Hinge joint $\rightarrow$ Between humerus and pectoral girdle
  3. Gliding joint $\rightarrow$ Between carpals
  4. Cartilaginous joint $\rightarrow$ Between frontal and parietal
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Joints are points of contact between bones, or between bones and cartilages.
  • Synovial joints are characterized by the presence of a fluid-filled synovial cavity between the articulating surfaces of the two bones. These joints help in locomotion and many other movements. Gliding joint is a type of synovial joint.
  • Gliding joints allow the bones to glide past one another in any direction along the plane of the joint -up and down, left and right, and diagonally.
  • The joint between carpals is gliding joint.
  • So, the correct answer is 'Gliding joint  → Between carpals'.

Polymerization reactions that produce many macromolecules are called _______ reactions.

  1. Hydrolytic

  2. Condensation

  3. Carboxylation

  4. Amination
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The condensation reaction is the type of polymerization reaction in which many monomers join together through bonds forming macromolecules of polymers by giving out byproducts majorly water. The example includes polypeptide chains of proteins or the formation of cellulose.

Hence, the correct answer is 'Condensation'.

The joint between carpal and metacarpal of thumb in primate mammals is

  1. Pivot joint

  2. Hinge joint

  3. Ball and Socket joint

  4. Saddle joint
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

There are six types of synovial joints. These are a pivot, hinge, saddle, plane, condyloid, and ball and socket joints. The pivot joint is a type of synovial joint that allows rotation. The joint between atlas and axis is pivot joint which allows the movement of the head back and forth. The hinge joint is a type of synovial joint which allows movement only in one axis, that is flexion and extension. Knee joint, ankle joint are examples of the hinge joint. Ball and socket joint allows rotation in multiple directions. In this type of joint, ball-shaped surface of one joint lies in the socket-like depression of another joint. The hip joint is an example of ball and socket joint. Saddle joint is the joint present between the carpal and metacarpal of thumb. It allows flexion, extension, adduction, abduction and circumduction movements. It provides stability and flexibility to bones.

Thus, the correct answer is option D.

The opening and closing of a door can be related to which of the following types of joints?

  1. Hinge joint

  2. Fixed joint

  3. Ball and socket joint

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • A joint is the part of the body where two or more bones meet to allow movement.
  • Hinge joint- the two bones open and close in one direction only (along one plane) like a door, such as a knee and elbow joints.
  • Hence The opening and closing of a door can be related to Hinge joint.
  • So, the correct answer is 'Hinge joint'.

  1. Hydra

  2. Tapeworm

  3. Leech

  4. Cockroach
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cockroach belongs to Arthropoda which is covered by an exoskeleton. The body is divided into three regions head, thorax and abdomen. They have a true coelom and have open spaces known as sinus. The segmentation is internal as well as internal while in hydra, tapeworm and leech only external segments are present
