In an emergency, which tissue helps in making quick decisions after analyzing the situation?

Detailed Solution: Question 2

Nervous tissue is found in the brain, spinal cord and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory and reasoning. So, nervous tissue helps in making quick decisions after analyzing.

Which body part is not composed of nervous tissue?

Detailed Solution: Question 3

Which body part is not composed of nervous tissue?
The correct answer is muscles.

Explanation:
The nervous tissue is responsible for transmitting signals throughout the body. It is found in various parts of the body, including the brain, spinal cord, and nerves. However, muscles are not composed of nervous tissue. They are made up of a different type of tissue known as muscle tissue.
Here is a detailed explanation:
1. Muscles: Muscles are responsible for movement and are composed of muscle tissue. Muscle tissue is made up of muscle fibers that contract and relax to produce movement. There are three types of muscles: skeletal muscles, which are attached to bones and allow voluntary movement; smooth muscles, which are found in the walls of organs and blood vessels and control involuntary movements; and cardiac muscles, which are found in the heart and control the heartbeat.
2. Nerves: Nerves are composed of nervous tissue and are responsible for transmitting signals between different parts of the body. They consist of nerve cells called neurons, which have the ability to generate and transmit electrical impulses. Nerves are found throughout the body and connect the brain and spinal cord to various organs and tissues.
3. Brain: The brain is the control center of the body and is composed of nervous tissue. It consists of billions of neurons that are responsible for processing and coordinating information from the senses, initiating and controlling movements, and regulating various bodily functions.
4. Spinal cord: The spinal cord is a long, cylindrical bundle of nervous tissue that extends from the base of the brain to the lower back. It is responsible for transmitting signals between the brain and the rest of the body. The spinal cord contains nerves that connect to different parts of the body and is protected by the bones of the spinal column.
In summary, while muscles play a crucial role in movement, they are not composed of nervous tissue. Nervous tissue is found in the brain, spinal cord, and nerves, which are responsible for transmitting signals throughout the body.

Which of the following does not signify striated muscle?

Detailed Solution: Question 4

Visceral muscle is also called the smooth muscle. 
Smooth muscle, neither striated in structure nor under voluntary control, is found within the walls of organs and structures such as the esophagus, stomach, intestine, bronchi, uterus, urethra, bladder, blood vessels and the arrector pili in the skin ( in which it controls erection of body hairs).
 

Test: Specialized Animals Tissues - Question 5
Save

Name the long part of neuron.

Detailed Solution: Question 5

The long part of a neuron is called the axon. The axon is a specialized extension of the neuron that transmits electrical impulses, known as action potentials, away from the cell body to other neurons, muscles, or glands. It plays a crucial role in cell-to-cell communication within the nervous system. Here is a detailed explanation of the different parts of a neuron:
1. Cell Body: Also known as the soma, the cell body contains the nucleus and other cellular organelles. It is responsible for the metabolic functions of the neuron.
2. Dendrites: These are the short, branch-like extensions of the neuron that receive incoming signals or information from other neurons. They play a role in integrating and processing these signals.
3. Axon: The axon is a long, slender projection that carries electrical impulses away from the cell body. It is covered by a fatty substance called myelin, which acts as an insulator and speeds up the transmission of impulses.
4. Terminal Branches: At the end of the axon, it branches out into many small terminal branches. These branches have specialized structures called synaptic terminals or boutons that form connections, known as synapses, with other neurons or target cells.
5. Synapse: The synapse is a junction between two neurons or between a neuron and a target cell. It is the site where the transmission of signals occurs through the release and reception of chemical messengers called neurotransmitters.
In summary, while the dendrites receive signals, the axon carries these signals away from the cell body to other neurons or target cells.

Test: Specialized Animals Tissues - Question 6

Which of the following is not a feature of muscle fibres found in the wall of blood vessels?

Detailed Solution: Question 6

Answer:
The correct option is A: Striated. The feature of muscle fibers found in the wall of blood vessels that is not present is being striated. Here are the features of muscle fibers found in the wall of blood vessels:
1. Uninucleate: Muscle fibers in the wall of blood vessels are uninucleate, meaning they have a single nucleus.
2. Involuntary: These muscle fibers are involuntary, meaning they are not under conscious control. They contract and relax automatically in response to signals from the nervous system.
3. Spindle-shaped: The muscle fibers in the wall of blood vessels are spindle-shaped. This shape allows them to contract and relax in a coordinated manner, helping to regulate blood flow and maintain blood pressure.
These features are characteristic of smooth muscle fibers, which make up the muscular layer of blood vessel walls. Unlike skeletal muscle fibers, which are striated, smooth muscle fibers lack the striations or banding pattern commonly seen in skeletal muscle.
Therefore, the correct answer is A: Striated.

Test: Specialized Animals Tissues - Question 7

Which of the following is not a feature of skeletal muscle?

Detailed Solution: Question 7

Muscles are cylindrical, straighted and multinucleate but they would not be branched because there are no multiple bone makes one bone though there are such bones that are multiple but are fragments. There are branched cells like neuron.

Test: Specialized Animals Tissues - Question 8

The contraction of muscle tissue is carried out by the action of

Detailed Solution: Question 8

Muscles are composed of two major protein filaments: a thick filament composed of the protein myosin and a thin filament composed of the protein actin. Muscle contraction occurs when these filaments slide over one another in a series of repetitive events.

Which of the following muscles are involuntary?

Detailed Solution: Question 9

Answer:

The correct answer is B: Cardiac and smooth muscles are involuntary.


Explanation:

Involuntary muscles are muscles that are not under conscious control, meaning they contract and relax without us having to think about it. The options and their explanations are as follows:



  • Option A: Cardiac and skeletal muscles - Skeletal muscles are voluntary muscles that we can control consciously, so this option is incorrect.

  • Option B (Correct): Cardiac and smooth muscles - Cardiac muscles are found in the heart and are responsible for pumping blood. Smooth muscles are found in the walls of organs and blood vessels. Both cardiac and smooth muscles are involuntary, so this option is correct.

  • Option C: Skeletal and smooth muscles - As stated earlier, skeletal muscles are voluntary, so this option is incorrect.

  • Option D: Only smooth muscles - This option is incorrect because cardiac muscles are also involuntary.


Therefore, the correct answer is B: Cardiac and smooth muscles are involuntary.

During a performance, if a dancer wants to stop her dancing, which muscles will execute this decision?

Detailed Solution: Question 10

Striated muscles can be controlled by one's own conscious will. Muscles present in our legs are striated muscles hence the following action will be executed by striated muscles present in the legs.
