Skeletal and Muscular System Questions

Multiple choice biology windows of knowledge human tongue organ of taste tongue : the organ of taste

The ............ muscles of the tongue are not attached to the bone.

  1. Extrinsic

  2. Intrinsic

  3. Posterior

  4. Lingual
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The eight muscles of the human tongue are classified as either intrinsic or extrinsic. The four intrinsic muscles act to change the shape of the tongue and are not attached to any bone. The four extrinsic muscles act to change the position of the tongue and are anchored to bone. Therefore, the correct answer is option B.

Multiple choice biology windows of knowledge human tongue organ of taste tongue : the organ of taste

Tongue taste is under control of

  1. Facial nerve

  2. Glossopharyngeal nerve

  3. Trigeminal nerve

  4. Autonomous nervous system
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The facial nerve (cranial nerve VII) controls taste sensation from the anterior two-thirds of the tongue. This region includes the tip, edges, and most of the tongue surface where sweet, salty, and sour tastes are primarily detected. The chorda tympani branch of the facial nerve carries these taste signals.

Hardest substance of the body is

  1. Bone

  2. Enamel

  3. Cartilage

  4. Tendon
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Hardest substance of the body is enamel. It is the thin outer covering of the tooth. It is composed of hydroxyapatite, which is a crystalline calcium phosphate. The color can vary from light yellow to a grayish white. It protects the tooth.

So, the correct answer is 'Enamel'.

Hips are attached to

  1. scapula

  2. sternum

  3. clavide

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

The pelvic girdle is located in the lower part of the trunk. It consists of three bones that are upper ileum, lower ischium and inner pubis, they fuse to form a stout hip bone. Ventral wall of the pubis has a small bone which is known as cotyloid. The acetabulum is formed by ilium, ischium and pubis, but in mammals, pubis is replaced by cotyloid bone.

So, the correct option is 'ilium'

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

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

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.

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

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'.
