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

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

  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
Reveal answer Fill a bubble to check yourself
B Correct answer
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.

  1. Pectoral girdle

  2. Ribs

  3. Pelvic girdle

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
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?

  1. Ribs

  2. Cranium

  3. Clavicle

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

Which one of the following is the correct matching of three items and their grouping category?

  1. Actin, myosin, rhodopsin : Muscle proteins

  2. Cytosine, uracil, thiamine : Pyrimidines

  3. Malleus, incus, cochlea : Ear ossicles

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

Actin and myosin are muscle proteins, while rhodopsin is a photoreceptor protein. 

Cytosine, uracil, and thiamine are pyrimidines, that along with purines make up the genetic material. 
Malleus, incus, and stapes together form the ear ossicles.

Cervical vertebrate differ from other vertebra in having.

  1. Spinous process

  2. Centrum

  3. Transverse process

  4. Transverse foramen
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Spinous process is a bony projection off the posterior (back) of each vertebra. It provides the point of attachment for muscles and ligaments of the spine.

Each vertebra consists of a ventral body, or centrum, surmounted by a Y-shaped neural arch. Together the centrum and neural arch surround an opening, the vertebral foramen, through which the spinal cord passes.

Transverse process is a small bony projection off the right and left side of each vertebrae. They function as the site of attachment for muscles and ligaments of the spine as well as the point of articulation of the ribs (in the thoracic spine). 

The cervical spine is much more mobile than the thoracic or lumbar regions of the spine. Unlike the other parts of the spine, the cervical spine has transverse foramina in each vertebra for the vertebral arteries that supply blood to the brain. Thus, option D is correct.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The vertebral column in adult man comprises of 26 bones- 

Cervical vertebrae (7), Thoracic vertebrae (12), Lumbar vertebrae(5), Sacrum (5 fused bones), Coccyx (3 to 5 fused bones). 
In a child, there are 33 separate vertebrae, the 9 in the sacrum and coccyx not yet being fused.

Ilium is the part of

  1. Small intestine

  2. Pectoral girdle

  3. Pulmonary tract

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

Pelvic girdle consists of two coxal bones. Each coxal bone is formed by the fusion of three bones ilium, ischium and pubis. At the point of fusion of the above bones is a cavity, called as acetabulum to which the thigh bone articulates. The two halves of the pelvic girdle meet ventrally to form the pubic symphysis containing fibrous cartilage.
