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

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.

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.

Obturator foramen is found in

  1. Frog's pelvic girdle

  2. Frog's pectoral girdle

  3. Rabbit's pelvic girdle

  4. Rabbit's pectoral girdle
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Looking to the bone, it reveals that the surface is not smooth but scarred with bumps, holes and ridges. These are surface markings, where muscles, tendons and ligaments attached, blood and lymph vessels and nerves pass. Some of the important depression and openings are 
(1) Fissure- narrow, cleft-like opening between adjacent parts of the bone. Example: Superior orbital fissure.
(2) Foramen- a bigger, round opening. Example: Foramen magnum in the skull. Obturator foramen is a large oval or irregularly triangular aperture in the hip bone (pelvic girdle of mammals), the margins of which are formed by the pubis and the ischium.
(3) Meatus- a relatively narrow tubular canal. Example: External auditory meatus.
(4) Groves and sulcus- are deep furrow on the surface of a bone or other structure. Example: Inter-vertebral and radial grooves of the humerus.
(5) Fossa- shallow depressed area. Example: Mandibular fossa.

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 i.e each half of pelvic girdle is made up of ilium, ischium, and pubis.
  •  At the point of fusion of the ilium, ischium and pubis bones there is a cavity called acetabulum to which the thigh bone (femur) articulates. Hence ilium is the part of pelvic girdle.
  • So,the correct answer is 'Pelvic girdle'.

Common to kidney and skeleton in mammals is

  1. Cortex

  2. Medulla

  3. Radius

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

  • The term 'pelvis' is common to both kidney and skeleton in mammals. In relation to the kidney, 
  • It can be described as a chamber in the kidney into which the urine drains from renal tubules before passing to the ureter. 
  • For skeleton, it is related to a pelvic girdle or hip girdle. Hence, Pelvis is Common to kidney and skeleton in mammals.
   So, the correct answer is 'pelvis'.

Which of the following cells give rise to the blastema in Hydra?

  1. Interstitial cells

  2. Mesenchymal cells

  3. Neoblasts

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

C- A mass of cell capable of growth and regeneration into organs or body parts is called as blastema that means these cells can grow in any type of cells except neurons.For the formation of blastema adult stem cells known as neoblasts are required before occurence of any regeneration.

Which of the following step of regeneration stops the bleeding at the site of amputation?

  1. Wound closure

  2. Redifferentiation

  3. Dedifferentiation

  4. Blastema formation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Regeneration process in higher animals involves a series of steps.1)Wound closure 2) Demolition and Defence 3)De-differentiation 4)Blastema Formation 5) Growth and 6)Re-differentiation.
  • WOUND HEALING: Amputation or injury to organ results in exposure of the interior tissues to the outside. Some cells in the injured region get destroyed. There may be bleeding at the injured surface. The blood soon clots and blocks further flow of blood to the outside. Hence bleeding is stopped.
  • Then the epidermal cells proliferate and migrate from all sides towards the center of the wound. Thus the epithelium forms a complete covering over the injured tissues underneath the blood clot. 
  • Hence Wound closure step of regeneration stops the bleeding at the site of amputation.
  • So, the correct answer is 'Wound closure'.

Reparative regeneration involves

  1. Replacement of lost part

  2. Growth of whole organism from fragment

  3. Healing of injury

  4. Both A and B
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Regeneration of damaged cells or tissues in the injured parts, in multicellular organisms is called reparative regeneration. It occurs in invertebrates and vertebrates.

So, the correct option is ‘Healing of injury’.

Which of the following forms the floor of the chest cavity?

  1. Lungs

  2. Membrane

  3. Diaphragm

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

  • The diaphragm is a thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest.
  •  It contracts and flattens when you inhale. 
  • This creates a vacuum effect that pulls air into the lungs.
  •  When you exhale, the diaphragm relaxes and the air is pushed out of lungs. Hence, diaphragm forms the floor of the chest cavity.
So, the correct answer is 'diaphragm'.

Ground tissue includes 

  1. Cortex and pericycle

  2. Pith

  3. Medullary ray

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The ground tissue of plants includes all tissues that are neither dermal nor vascular. It can be divided into three types parenchyma, collenchyma, and sclerenchyma. Cortex is composed of thin-walled parenchymal cells. The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the style of plants.

So, the correct answer is 'Cortex and pericycle'.
