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

  1. Ball and socket

  2. Gliding

  3. Hinge

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

  1. Neck

  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.

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

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'.
Multiple choice evs our skeletal system and the skin bones and movements joints in the human body joints bones

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'.

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'.

Total number of skull skeleton bones in human are

  1. 29

  2. 49

  3. 39

  4. 19
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The human skull is a bony structure that supports the face and creates a cavity for the brain and protects it. The skull is made up of 8 cranial bones, 14 facial bones and 6 middle ears and 1 hyoid bones. So, the total number of bones in the skull are 29 bones.

Which of the following is made up of a single bone in a mammal?

  1. Carpals

  2. Hyoid

  3. Upper jaw

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The lower jaw of mammals consists of only one bone, the dentary whereas jaws of other vertebrates are composed of more than one bone. This bone joins the skull at the squamosal bone. This anterior bone of the lower jaw bears the teeth. Hence option A is correct.

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

Which of the following does not have corresponding bones?

  1. Pelvic and pectoral girdle

  2. Atlas and coccyx

  3. Carpals and tarsals

  4. Humerous and femur
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The atlas ($C _1$) is the most superior (first) cervical vertebra of the spine. The atlas's chief peculiarity is that it has no body. It is ring like and consists of an anterior and a posterior arch and two lateral masses. The coccyx commonly referred to as the tailbone is the final segment of the vertebral column in humans and apes. It comprises of three to five separate or fused coccygeal vertebrae below the sacrum. As, both atlas and coccyx are the two first and last bones respectively of the vertebral column they do not have corresponding bones.

So, the correct answer is 'Atlas and coccyx'

E Correct answer
Explanation

Of the 206 bones in the human body, 22 bones are in the skull. The skull consists of 8 cranial bones and 14 facial bones. The hyoid bone (lingual bone) is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. The middle ear contains three tiny bones known as the ossicles: malleus, incus, and stapes.
