  1. Tip of nose

  2. Ear ossicles

  3. Vertebrae

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

  • The kind of tissue that forms the supportive structure in our pinna (external ears) is also found in tip of the nose. 
  • As External pinna is made up of elastic cartilage. 
  • It is passage towards middle ear. Hence, The supportive structure of our pinna is also found in the tip of the nose.
So, the correct answer is 'tip of nose'.

A joint made for power is

  1. Knee joint

  2. Suture in cranium

  3. Joint between vertebrae

  4. Mandibular joint
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • The lower jaw is made up of a single bone called mandible.
  • The mandible is the longest and strongest bone in the face. It forms the lower jaw and holds the teeth in place.
  •  Movement of the lower jaw opens and closes the mouth and also allows for the chewing of food. The lower set of teeth in the mouth is rooted in the lower jaw.
  • The mandibular joint is a joint made for power. It connects the lower jaw bone to the skull.
  • So, the correct answer is 'Mandibular joint'.

The characteristics and an example of a synovial joint in humans is :

  1. Characteristics - Fluid cartilage between two bones, limited movements, Examples - Knee joint

  2. Characteristics - Fluid filled between two joints, provides cushion, Examples - Skull bones

  3. Characteristics - Fluid filled synovial cavity between two bones, Examples - Joint between atlas and axis

  4. Characteristics - Lymph filled between two bones, limited movement, Examples - Gliding joint between carpals
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
All articulations between bones that help in a certain kind of movement, are placed at a distance from each other to prevent friction between them during movement. This space between the two bones is filled with synovial fluid that also helps reduce friction. For example the ball and socket joint of the pelvic girdle, the pivotal joint between the atlas and the axis
So, the correct answer is 'Characteristics - Fluid filled synovial cavity between two bones, Examples - Joint between atlas and axis'

Which one of the following secretes a watery fluid for lubricating and cushioning the joint?

  1. Ligament

  2. Cartilage

  3. Tendon

  4. Synovial membrane
Reveal answer Fill a bubble to check yourself
D 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.
  • The synovial cavity is covered by the synovial membrane which secretes a watery fluid called synovial fluid for the lubricating and cushioning joint.
  • So, the correct answer is 'Synovial membrane'.

Synovial joints may be classified into subtypes according to

  1. Shape

  2. Amount of synovial fluid

  3. Number of bones

  4. Amount of cartilage
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Based on the movement ability, fibrous and cartilaginous joints are functionally classified as a synarthrosis or amphiarthrosis, the synovial joints are classified on the basis of shape.

So, the correct option is 'Shape'.

Joints between human skull bones are

  1. Saddle

  2. Gliding

  3. Imperfect

  4. Immovable
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A. Saddle joint allows movement on many directions and is present between carpals and metacarpals of the human thumb.
B. Gliding joint allows movement only in one direction and is present between tarsal and carpals.
C. Imperfect joint or Cartilaginous joint are joined together with the help of a disc of cartilage which restricts the movement and shows limited or slight movement and is present between the adjacent vertebrae of the vertebral column and in pubic symphysis.
D. The immovable joint does not allow any movement because the bones are firmly fixed together by strong collagen fibers and are present in the skull bones called as sutures.
So, the correct option is D.

  1. Acetabulum

  2. Neural arch

  3. Glenoid cavity

  4. Olecranon fossa
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The glenoid cavity of scapula is a part of the shoulder. It is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula.
So correct answer is option C.Glenoid cavity.

Synovial fluid is secreted by

  1. Blood

  2. Cartilage

  3. Bone

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

Membranes are thin pliable layers of epithelial and/or connective tissue. They line body cavities, cover surfaces, connect, or separate regions, structures and organs of the body. 

The three kinds of membranes are mucous, serous and synovial. 
Synovial membrane, unlike to other membranes does not contain epithelium. Therefore, it is not the epithelial membrane. It lines the cavities of the freely movable joints. Like serous membrane, it lines structures, that do not open to the exterior. Synovial membranes secrete the synovial fluid that lubricates articular cartilage at the ends of bones as they move at joints.

Sacroiliac joint is

  1. Movable

  2. Immovable

  3. Imperfect

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
The sacroiliac joint connects the sacrum (triangular bone at the bottom of the spine) with the pelvis (iliac bone, that is part of the hip joint) on each side of the lower spine. It transmits all the forces of the upper body to the pelvis and legs. There is not a lot of motion in the joint and it is very strong and stable.
