Which of the bone structures protect the lungs in our body?

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

  1. Rib cage

  2. Skull

  3. Vertebral column

  4. All of the above

Show answer
Correct Option: A
Explanation:

All human beings respire air through the process of inhalation and exhalation. That is inhaled passes through the entire respiratory tract and reaches the lungs. Lungs are respiratory organs located in the thoracic cavity of our body.  The partial pressure of the air inside the lungs guides the process of inhalation and exhalation. They are surrounded by ribs. Ribs are bones that together form the rib cage in our thorax. The rib cage protects the lungs.

So, option A "Rib cage" is the correct answer.

Vertebral column is made up of

  1. Bones

  2. Tissue of muscles

  3. Neurons

  4. Chlorophyll

Show answer
Correct Option: A
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

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

  1. Ribcage

  2. Pelvic bones

  3. Shoulder bones

  4. All of the above

Show answer
Correct Option: B
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'.

  1. Ribs and thoracic vertebrae

  2. Ribs and sternum

  3. Ribs, sternum and vertebrae

  4. Ribs, sternum and thoracic vertebrae

Show answer
Correct Option: D
Explanation:

The dorsal, ventral and lateral Part of thoracic basket are respectively formed of thoracic vertebrae, sternum and ribs`.

Innominate is a

  1. Nerve

  2. Muscle

  3. Animal

  4. A Part of skeleton and honorary

Show answer
Correct Option: D
Explanation:

Half of the vertebrate pelvic girdle consists of three bones ilium, ischium and Pubis which fuse together in adult to be called innominate bone Chip bone).

Human vertebral column has

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

  1. Four curves

  2. No curves

  3. Three curves

  4. Two curves

Show answer
Correct Option: A
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?

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

  1. Breastbone

  2. Backbone

  3. Shoulder bone

  4. Both A and B

Show answer
Correct Option: D
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?

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

  1. Bones

  2. Muscles

  3. Blood

  4. Both A and B

Show answer
Correct Option: D
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.

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. 

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

  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

Show answer
Correct Option: A
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'.

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

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

  1. Saddle joint

  2. Fibrous joint

  3. Cartilaginous joint

  4. Pivot joint

Show answer
Correct Option: D
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'
