Reveal answer Fill a bubble to check yourself
A Correct answer
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'

  2. Forward

  3. Downward backward

  4. Bending

  5. Straightening

A Correct answer
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).

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 .
