Skeletal and Muscular System Questions

Multiple choice biology the flower structure of a bisexual flower growth and development in plants basics of leaf and flower

Structure equivalent to perianth is

  1. Superior palea

  2. Inferior palea

  3. Glumes

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

The term perianth is used to refer to the condition when the calyx and corolla are not differentiated. In grasses, the similar condition is seen by the presence of lodicules, that are situated below the ovary. 

A. & B. Palea are bracts present in spikelets of the grasses.
C. Glumes are the involucre in the inflorescence of a spike.
D. Lodicules are the covering present below the ovary, similar to the perianth.
Hence, the correct answer is 'Lodicules'

Multiple choice biology life processes: control and coordination structure and function of brain human brain nervous and endocrine system in humans

In Human beings, the cranium is formed by

  1. Eight bones of which two are paired

  2. Fourteen bones of which six are paired

  3. Ten bones of which two are paired

  4. Twelve bones of which four are paired
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The human cranium consists of 8 bones: frontal (1), parietal (2), temporal (2), occipital (1), sphenoid (1), and ethmoid (1). This totals 8 bones with two pairs (parietal and temporal).

Which of the following body part has more number of bone that others?

  1. Skull

  2. Chest

  3. Forelimb

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

The human skeleton is the internal framework of the body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. 

So, the correct option is ‘Skull’.

Which joint is more flexible in males than females?

  1. Public symphysis

  2. Deltoid ridge

  3. Deltoid tuberosity

  4. Sacroiliac joint
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'

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 .

Total number of vertebra in man is

  1. 30

  2. 33

  3. 40

  4. 35
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.

Cervical vertebrae are characterized by the presence of

  1. Long neural spine

  2. Odontoid process

  3. Vertebral-arterial-canals

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

There are 7 cervical vertebrae. All cervical vertebrae have apertures in their transverse processes, known as Foramina transversalis, which form vertebro-arterial-canals on either side for vertebral artery to pass through to supply brain and spinal cord.
