Skeletal and Muscular System Questions

Multiple choice botany stem - external morphology morphology of the stem stem shoot system in plants

Unbranched, erect, cylindrical stout axis with distinct nodes and internodes and with jointed appearance is called as

  1. Runner

  2. Sucker

  3. Culm

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

Erect, unbranched stems with distinct nodes and internodes are called culms, nodes are swollen giving a jointed appearance. For example, bamboo.

Multiple choice zoology option a: neurobiology and behaviour structure and function of ear perception of stimuli neural control and coordination

The middle ear and internal ear of mammals are enclosed in which of the following bones __________________.

  1. Tympanic bulla and periotic bone (Temporal bone)

  2. Ethmoid

  3. Tympanic bulla

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

The auditory bulla (pl. bullae) is a hollow bony structure on the ventral, posterior portion of the skull that encloses parts of the middle and inner ear. In most species, it is formed by the tympanic part of the temporal bone.

Multiple choice

Where is the smallest bone in the body?

  1. Ear

  2. Nose

  3. Toe

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

The stapes, also known as the stirrup, is the smallest and lightest bone in the human body. It is located in the middle ear.

Multiple choice zoology grades of body organisation characteristics of annelida and arthropoda characteristics of platyhelminthes and aschelminthes basis of classification in animals basis of the classification of animals criteria for animal classification

The evolution of this structure lead to the human lineage.

  1. Bone

  2. Cranium

  3. Jaws

  4. Notochord

  5. Vertebrae
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The notochord is the defining structure forming in all chordate embryos. In humans beings, the notochord is formed in the third week and eventually replaced by the vertebral column. 

Multiple choice disorders of muscular system disorders of muscle and skeleton movement and locomotion in man locomotion and movements biology

Select the correct statement with respect to locomotion in human:

  1. The joint between adjacent vertebrae is a fibrous joint

  2. A decreased level of progesterone cause osteoporosis in old people

  3. Accumalation of uric acid crystals in joints cause their inflammation
  4. The vertebral column has $10$ thoracic vertebrae
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Locomotion is the process of movement of an organism from one place to another.

  • The fibrous joint is a fixed joint and is present in the bones of the skull while the synovial joint is present in the bones of the vertebrae making it movable.
  • Progestrone is a hormone responsible for the menstruation cycle and pregnancy.
  • The process of accumulation of the uric acid in the form of crystals at the place of joints causes inflammation and joint pain, this condition is termed as gout.
  • The vertebral column has 33 vertebrae out of which 27 presacral vertebrae, 7 cervical, 12 thorasic, and 5 lumbar vertebrae are found.

So, the correct option is 'Accumulation of uric acid crystals in joints cause their inflammation'

Still disease is a type of

  1. Arthritis

  2. Rickets

  3. Sprain

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

Still's disease is an inflammation of joints causing arthritis which produces symptoms such as fever, rash, and joint pains. If it is not treated, the inflammation may destroy joints particularly the wrist joints. Steroids are used in treating this rare disease.

So, the correct answer is 'Arthritis'

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.
