Questions Related to human skeleton system

Which joint is more flexible in males than females?

zoology movement and locomotion in man bones and movements our skeletal system and the skin human skeleton system

  1. Public symphysis

  2. Deltoid ridge

  3. Deltoid tuberosity

  4. Sacroiliac joint

Show answer
Correct Option: A
Explanation:

The hip girdle is located in the lower part of the trunk. 

It is made up of three bones that are upper ileum, lower ischium and the pubis.
The acetabulum is formed by ileum, ischium and pubis but in mammals, the pubis is replaced by the cotyloid bone.

The pubic symphysis is present in mammals. The two innominate bones and sacrum together form a sort of bowel.
This is also an adaptation for the upright posture of the human body. The female pelvis is larger and has a broader front and larger bottom opening than the male pelvis. This is an adaptation for childbirth.

So, the correct option is 'Public symphysis'

Collar bone is 

zoology movement and locomotion in man bones and movements our skeletal system and the skin human skeleton system

  1. Scapula

  2. Stapes

  3. Coracoid

  4. Clavicle

Show answer
Correct Option: D
Explanation:

The clavicle is a long bone between the shoulder blade and the sternum and is known as the collar bone. They are called so because their presence seems to appear much like a collar. 


So, the correct answer is 'clavicle'.

Supination means turning plan

  1. Upward

  2. Forward

  3. Downward backward

  4. Bending

  5. Straightening

Show answer
Correct Option: A
Explanation:

Pronation and supination are a pair of unique movements possible only in the forearms and hands, allowing the human body to flip the palm either face up or face down. The muscles, bones, and joints of the human forearm are specifically arranged to permit these unique and important rotations of the hands. So, the correct option is "A" (Upward).

Correct Option: A

Out of the following pairs of the human skeletal parts, identify the wrongly matched pair

zoology movement and locomotion in man bones and movements our skeletal system and the skin human skeleton system

  1. Humerus and ulna - Appendicular skeleton

  2. Clavicle and glenoid cavity - Pelvic girdle

  3. Sternum and ribs - Axial skeleton

  4. Malleus and stapes - Ear ossicles

Show answer
Correct Option: B
Explanation:

The human skeleton is made up of 206 bones of which the vertebral column is made up of 33 bones. The pelvic girdle that is a part of the appendicular skeleton. Two hip bones along with sacrum and coccyx form the pelvic girdle which surrounds the pelvic cavity. The humerus and ulna from the elbow joint, the clavicle and glenoid cavity form the bones of the shoulder joint.

Acromion process is characteristically found in the ______ of mammals.

zoology movement and locomotion in man bones and movements our skeletal system and the skin human skeleton system

  1. Pectoral girdle

  2. Ribs

  3. Pelvic girdle

  4. None of these

Show answer
Correct Option: A
Explanation:

A.Acromian process-is found in pectoral girdle of mammals. Pectoral girdle consists of scapula and clavicle. The scapula consists of a sharp ridge, the spine and a triangular body, The end of the spine projects as a flattened and expanded process called acromian.
B.Ribs-

a series of slender curved bones articulated in pairs to the spine (twelve pairs in humans), protecting the thoracic cavity and its organs.
C.Pelvic girdle-
in vertebrates the enclosing structure formed by the bony pelvis, providing attachment for the hindlimbs or pelvic fins.
So Correct answer is option A.Pectoral girdle.

Which of these is a part of appendicular skeleton?

zoology movement and locomotion in man bones and movements our skeletal system and the skin human skeleton system

  1. Ribs

  2. Cranium

  3. Clavicle

  4. Vertebrae

Show answer
Correct Option: C
Explanation:

Appendicular skeleton is the part of the skeleton of vertebrates. It consists of bones that support the appendages. Ther are four parts of appendicular skelton:
1) Pectoral girdle - Clavicle and scapula 

2) lower limb
3) upper limb
4) Pelvic girdle- hip bones
Hence , option C is correct .
