Multiple choice biology animal tissue types of neuron nervous tissue neural tissues

The nerves that carry the messages towards the CNS from sense organs are __________.

  1. Afferent neurons

  2. Efferent neurons

  3. Interneurons

  4. none of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
A. Neurons that receive information from our sensory organs (e,g. eye, skin) and transmit this input to the central nervous system (CNS) are called afferent neurons.
B. Neurons that send impulses from the CNS to our limbs and organs are called efferent neurons.
C. Interneurons create neural circuits, enabling communication between sensory or motor neurons and the CNS.
So, the correct answer is 'Afferent neurons'.

Neural proteins are mainly synthesized in__________

  1. Cell body of neuron

  2. Axon

  3. Dendrites

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

  • The human body is made up of trillions of cells. Cells of the nervous system called nerve cells or neurons, are specialized to carry "messages" through an electrochemical process. Neurons carry out basic cellular processes such as protein synthesis and energy production.
  • Protein synthesis in the extensions of nerve cells, called dendrites, Local protein synthesis in dendrites, not in the cell body of nerves, provides the ability to respond rapidly and selectively to external stimuli. 

So the answer is 'Dendrites'.

Largest number of cell bodies of neuron in our body are found in the_________.

  1. Retina

  2. Spinal cord

  3. Brain

  4. Tongue
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The largest number of cell bodies of neurons in our body is found in the brain.
The human brain is the main organ of the human nervous system. It is located in the head, protected by the skull. It has the same general structure as the brains of other mammals, but with a more developed cerebral cortex.
The human brain is composed of neurons, glial cells, and blood vessels.
Multiple choice biology animal tissue muscle tissue structure of protein muscle tissues

Which of the following ions has a regulatory role in internal movements?

  1. Calcium

  2. Magnesium

  3. Iron

  4. Zinc
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Sarcoplasmic reticulum is similar to endoplasmic reticulum present in other cells. It is present in sarcoplasm (cytoplasm of the muscle cell) of the muscle fiber (muscle cell).
  • The main function of the Sarcoplasmic reticulum is to store calcium ions (Ca2+).
  • When nerve signal reaches the neuromuscular junction it triggers the release of calcium from sarcoplasmic reticulum which in turn facilitates muscle contraction by binding to troponin. thus causing tropomyosin to shift from the face of the actin filament to which myosin heads need to bind to produce a contraction.
  • Hence Calcium ions have a regulatory role in internal movements.
  • So, the correct answer is 'Calcium'.
Multiple choice biology animal tissue muscle tissue structure of protein muscle tissues

All the following are examples of connective tissue except _______________.

  1. Tendons

  2. Ligaments

  3. Muscle

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

Connective tissue serves a connecting function. It supports and binds other tissues in the body. This tissue typically has cells scattered throughout an extracellular matrix of fibrous proteins and glycoproteins attached to a basement membrane. The primary elements of connective tissue include a ground substance, fibres, and cells. Adipose tissue is a type of specialised connective tissue and the ligaments and the tendons belong to the dense type of connective tissue while the muscle belongs to another class of tissues namely muscle tissue which are different from the connective tissue.
So, the correct answer is 'Muscle'.
Multiple choice biology animal tissue muscle tissue structure of protein muscle tissues

A muscle is rich in 

  1. Fat

  2. Protein

  3. Vitamins

  4. Carbohydrate
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A muscle is rich in protein. The muscle cells contain protein filaments of actin and myosin. Actin is a thin filament and myosin is a thick filament. These protein filaments slide past one another to produce contraction. This results in change in length and shape of the cell.

Thus, the correct answer is 'Protein.'

Movement in body are brought about by?

  1. Muscular tissue

  2. Epithelial tissue

  3. Bones

  4. Tendon and ligaments
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The main function of the muscular system is movement. Muscles are the only tissue in the body that has the ability to contract and therefore move the other parts of the body & the maintenance of the body posture & body position.

So, the correct option is 'Muscular tissue'.

Contractile proteins are found in_________________.

  1. Bones

  2. Blood

  3. Muscles

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

From all the above options, only muscle has a property of contraction. Muscle possess contractile proteins named, acitn and myosin on myofibrils. Hence, option C is correct.
