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 .

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

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

  1. Actin, myosin, rhodopsin : Muscle proteins

  2. Cytosine, uracil, thiamine : Pyrimidines

  3. Malleus, incus, cochlea : Ear ossicles

  4. None of these

Show answer
Correct Option: B
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.

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

  1. Spinous process

  2. Centrum

  3. Transverse process

  4. Transverse foramen

Show answer
Correct Option: D
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.
