Multiple choice evs bones skeletal system and muscles assimilation of food components and importance of food

Vertebral column is made up of

  1. Bones

  2. Tissue of muscles

  3. Neurons

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

The backbone or vertebral column or spine is a part of the axial skeleton. The backbone is made up of the bones, muscles, tendons, and other tissues that reach from the base of the skull to the tailbone. The backbone encloses the spinal cord and the fluid surrounding the spinal cord.

The most appropriate answer is that the vertebral column is made up of bones.

The enclosed body part below the stomach is occupied by

  1. Ribcage

  2. Pelvic bones

  3. Shoulder bones

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The stomach is a muscular organ located on the left side of the upper abdomen.
  • The bones of the pelvis or pelvic bones are the hip bones, sacrum, and coccyx. Each hip bone contains three bones— the ilium, ischium, and pubis.
  • The pelvis  It's located between the abdomen and the legs. This area provides support for the intestines and also contains the bladder and reproductive organs.
  • Hence The enclosed body part below the stomach is occupied by the pelvis.
  • So, the correct answer is 'Pelvis'.

Human vertebral column has

  1. Four curves

  2. No curves

  3. Three curves

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

  • The vertebral column in adults have four curvatures and are classified as- primary or secondary curvatures.
1) The primary curves are the ones which are retained from the fetal curvature 
  • It is retained in two regions as the thoracic curve which consists of thoracic vertebrae and the sacrococcygeal curve.
2) Whereas, the secondary curvatures develop gradually after the birth as the child learns to sit upright, stand and walk.
  • The lumbar curve of the lower back is a secondary curvature.
  • So, the correct answer is 'Four curves'.

Which of the following bones helps in the formation of ribcage?

  1. Breastbone

  2. Backbone

  3. Shoulder bone

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The breastbone is the flat bone which is located at the center of the chest. Ribs are attached to it forming ribcage. Backbone is the vertebrae extending from the skull to pelvis. The ribs are attached to vertebrae from behind.

Thus, the correct answer is option D.

Which of the following helps to maintain the structural framework of the body?

  1. Bones

  2. Muscles

  3. Blood

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The bones and muscles together form the structural framework of the body. The skeleton  constitutes of bones and various types of joints. Muscles are attached to the bones, providing the strength needed for locomotion (movement).

Blood helps to transport gases like oxygen and carbondioxide, hormones, etc. to various parts of the body.
Thus, the bones and muscles together help to maintain the structural framework of the body by providing strength and power to perform work activities.

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

Read the given statements and select the correct option.
Statement 1 : Articulation between the occipital condyles and the atlas vertebra forms a hinge joint.
Statement 2 : It permits the head to move in one plane only, i.e., nodding of head. 

  1. Both statements 1 and 2 are correct

  2. Statement 1 is correct but statement 2 is incorrect

  3. Statement 1 is incorrect but statement 2 is correct

  4. Both statements 1 and 2 are incorrect
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Articulation between the occipital condyles and the atlas vertebra forms a hinge joint, it permits the head movement in one plane.

So, the correct option is 'Both statements 1 and 2 are correct'.

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

Which of the following joints is formed between atlas and axis vertebrae?

  1. Saddle joint

  2. Fibrous joint

  3. Cartilaginous joint

  4. Pivot joint
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Pivot joint is present between atlas and axis vertebrae. there is a pivot articulation between the odontoid process of the axis and the ring formed by the anterior arch and the transverse ligament of the atlas.
So, the correct option is 'Pivot joint' 
Multiple choice evs bones joints in the human body our skeletal system and the skin joints

The joint of femur with pelvic girdle is:

  1. hinge joint

  2. non-movable joint

  3. pivot joint

  4. ball and socket joint
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The joint of the femur with pelvic girdle is a synovial - ball and socket joint. Where the ball like projection of the femur fits into the cup like acetabulum of the pelvic bone, with the movement being 360$^0$ and the gap between the joint filled by synovial fluid.

So, the correct answer is 'ball and socket joint'

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

Which one of the following pairs of structures is correctly matched with their correct description ?

  1. Tibia and fibula Both form parts of knee joint

  2. Joint between Pivot joint atlas and axis

  3. Shoulder joint Ball and socket type of joint and elbow joint

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Tibia and fibula are two long bones in the lower leg tibia connect to the knee joint while the fibula is located below the knee joint but is not part of the joint itself, while the joint between atlas and axis is pivot type of joint.

So, the correct option is 'Joint between Pivot joint atlas and axis'.

What is the type of movable joint present between the atlas and axis ?

  1. Pivot

  2. Saddle

  3. Hinge

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

Pivot joint helps in turning movements. One bone is fixed and second articulate. This is generally seen in the Atlas and axis of the skull rotate with the axis vertebra also known as an atlantoaxial joint.

So, the correct option is 'Pivot'

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

Which one of the following options is incorrect ?

  1. Hinge joint between humerus and pectoral girdle

  2. Pivot joint between atlas, axis and occipital condyle

  3. Gliding Joint between the carpals

  4. Saddle joint between carpel and metacarpals of thumb
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

There are many joints present in the skeleton. Joint is a point of contact between two bones. The various type of joints present in the body are-

Ball and socket joint-
Ball of one bone articulate in the socket of another bone. Head of the humerus and glenoid cavity of the pectoral girdle,  femur and acetabulum, the joint between incus and stapes.
Hinge joint-
movement is possible in one direction only. Joint of malleus and incus, knee joint, elbow joint, articulation joint of the lower jaw.
Pivot joint- 
helps in turning moment. One bone is fixed and second articulate. Atlas and axial of skull rotate with Axis vertebra 
Gliding joint-
limited movement in all direction. Radius and ulna
Saddle joint- 
It is a ball and socket like a joint but not developed fully. Metacarpals of thumb and carples of hand.
So, the correct option is 'Hinge joint between humerus and pectoral girdle'
