The joints between the carpal bones are:

evs our skeletal system and the skin bones and movements joints in the human body joints bones

  1. gliding joints

  2. hinge joints

  3. saddle joints

  4. pivot joints

Show answer
Correct Option: A
Explanation:

The joints between the carpal bones are 'gliding joints'.

Elbow joint is an example of .......... type of joint.

evs our skeletal system and the skin bones and movements joints in the human body joints bones

  1. Ball and socket

  2. Gliding

  3. Hinge

  4. Pivot

Show answer
Correct Option: C
Explanation:
In hinge joints, the articulating ends of the bones fit together like a hinge on a door, and movement is therefore restricted to flexion and extension (movement only in one plane). 
The elbow joint is an example, which permits only flexion and extension of the forearm. Other examples of hinge joints are knee joint, ankle joint and joints between the phalanges of the fingers and the toes.
So, the answer is C.

Hinge joints are present in the ........... region.

evs our skeletal system and the skin bones and movements joints in the human body joints bones

  1. Neck

  2. Shoulder

  3. Elbow

  4. Skull

Show answer
Correct Option: C
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

evs our skeletal system and the skin bones and movements joints in the human body joints bones

  1. Osteology

  2. Chondrology

  3. Craniology

  4. Arthrology

Show answer
Correct Option: D
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.

evs our skeletal system and the skin bones and movements joints in the human body joints bones

  1. Gomposes $\rightarrow$ Intercarpal joints

  2. Syndesmoses $\rightarrow$ Joint between tibia and fibula

  3. Symphysis $\rightarrow$ Joint between vertebrae

  4. Synchondrosis $\rightarrow$ Epiphyseal plate

Show answer
Correct Option: A
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.

Show answer
Correct Option: C
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.

evs our skeletal system and the skin bones and movements joints in the human body joints bones

  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

Show answer
Correct Option: C
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.

evs our skeletal system and the skin bones and movements joints in the human body joints bones

  1. Hydrolytic

  2. Condensation

  3. Carboxylation

  4. Amination

Show answer
Correct Option: B
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

evs our skeletal system and the skin bones and movements joints in the human body joints bones

  1. Pivot joint

  2. Hinge joint

  3. Ball and Socket joint

  4. Saddle joint

Show answer
Correct Option: D
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?

evs our skeletal system and the skin bones and movements joints in the human body joints bones

  1. Hinge joint

  2. Fixed joint

  3. Ball and socket joint

  4. All of the above

Show answer
Correct Option: A
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'.
