Skeletal and Muscular System Questions

Multiple choice zoology skeleton and joints introduction to movement introduction to locomotion movement

Which of the following type of movement is supported by joints?

  1. Bending

  2. Partial rotation

  3. Complete rotation

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

There are various types of joints in the human body.

1. Hinge joint: Hinge joint is a common class of synovial joint that includes the ankle, elbow and knee joints. Maximum rotation is 180$^o$. (partial rotation)
2. Ball and socket joints provide maximum rotation i.e. a full circle (complete rotation). Example: Shoulder joint, hip joint
3. The joints of the vertebrae provide a scope for bending movement, such joints are partially movable i.e. diarthrosis joints.
Thus, the types of movements supported by the joints are bending, partial rotation and complete rotation.

Multiple choice zoology skeleton and joints introduction to movement introduction to locomotion movement

Which of the following parts of the body shows maximum movements?

  1. Joints

  2. Muscles

  3. Bones

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Joints are the areas where two or more bones meet.
  • Joints are of three types. They are Synovial Joints, Fibrous Joints, and Cartilaginous Joints
  • Joints help in bringing about movements in different parts of the body. 
  • Synovial joints are the freely movable joints and show maximum moments in the body.
  • Hence parts of the body that shows maximum movements are joints.
  • So, the correct answer is 'Joints.
Multiple choice zoology the endocrine system introduction to human endocrine system endocrine system and hormone coordination in human beings- chemical control

Structure responsible for formation of sigmoid notch is

  1. Olecranon process of humerus

  2. Olecranon process of femur

  3. Olecranon process of radius ulna

  4. Olecranon process of tibia fibula
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ulna projects beyond the radius as an oleander process which has a deep sub terminal sigmoid notch for articulation with the distal end of humerus.

$1$. Femur is the longest bone in human body.
$2$. Stapes is the smallest bone found in ear.
$3$. Stapedius is the smallest muscle in our body.
$4$. Turbinal bones can be traced in forelimbs.
Which of the statements given are correct?

  1. $3$ and $4$
  2. $1, 2$ and $4$
  3. $2$ and $3$

Multiple choice general knowledge our skeletal system and the skin other systems in the body introduction to skeletal system busy at work - our internal organs

Consider the following statements:
$1$. Calcium phosphate is found in bones is largest in amount.
$2$. Longest bone is found in thigh region of human body.
$3$. Longest bone found in man is Femur.
Which of the statement(s) given is/are true about bone?

  1. Only $1$
  2. Only $2$
  3. $1, 2$ and $3$

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

Calcium phosphate is the primary mineral in bones. The femur is the longest bone and is located in the thigh.

Multiple choice general knowledge our skeletal system and the skin other systems in the body introduction to skeletal system busy at work - our internal organs

Consider the following statements:
$1$. Humerus is found in human leg.
$2$. Smallest bone of human body is Stapes.
Which of the statement(s) given is/are correct?

  1. Only $1$
  2. Only $2$
  3. $1$ and $2$

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

The humerus is the bone of the upper arm, not the leg. The stapes is indeed the smallest bone in the human body.

Multiple choice general knowledge our skeletal system and the skin other systems in the body introduction to skeletal system busy at work - our internal organs

Study the following statements:
$1$. Study of bones is called Osteology.
$2$. Process of bone formation is known as Ossification.
$3$. Sesamoid bones are formed by ossification in tendons.
Which of the statements given are correct about bones?

  1. $1, 2$ and $3$
  2. $2$ and $3$
  3. $1$ and $3$
  4. $1$ and $2$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Osteology is the study of bones. Ossification is the process of bone formation. Sesamoid bones are small, round bones embedded in tendons.

Multiple choice general knowledge our skeletal system and the skin other systems in the body introduction to skeletal system busy at work - our internal organs

Study the following statements:
$1$. Tendons connect bone to muscles.
$2$. Bone forming cells are osteoblasts.
$3$. Ligament connect bone to bone.
Which of the statements given are correct?

  1. $1$ and $2$
  2. $2$ and $3$
  3. $1, 2$ and $3$

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

Tendons connect muscles to bones, ligaments connect bones to bones, and osteoblasts are indeed the cells responsible for bone formation. All three statements are biologically accurate.

Multiple choice general knowledge our skeletal system and the skin other systems in the body introduction to skeletal system busy at work - our internal organs

Bones of old persons are brittle and fractured more readily occur because they contain more _________.

  1. lacunae

  2. organic matter

  3. inorganic matter

  4. bone marrow
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Bone brittleness in the elderly is primarily due to a decrease in organic collagen content and an increase in the relative proportion of inorganic mineral salts, which makes the bones harder but less flexible.

Which one of the following is the correct description of a certain part of a normal human skeleton?

  1. Parietal bone and the temporal bone and the skull are joined by fibrous joint.

  2. First vertebrae is axis, which articulates with the occipital condyles.

  3. The 9th and 10th pairs of ribs are called the floating ribs.

  4. Glenoid cavity is a depression to which the thigh bone articulates.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A suture is a type of fibrous joint, which only occurs in the skull. These joints are synarthroses. One parietal bone is located on each side of the skull just behind the frontal bone. The temporal bones are situated at the sides and base of the skull, and lateral to the temporal lobes of the cerebrum.
