The brain has no
Tendons are the connective tissue, which joins skeletal muscles to bones. Hence nervous tissue is absent in a tendon. Nervous tissue's main work is to transmit messages within our body.
Conversely, solid organs, such as the lungs, liver, and spleen, have fewer free endings and are not highly sensitive to pain. Hence, they can deteriorate without the individual's becoming very aware of it.
The human body contains special nerve endings called sensory receptors that enable you to “feel” things. These receptors are not located only in your skin. They're also found in muscles, joints, blood vessels and internal organs.
The brain itself is a not a muscle. It contains blood vessels and nerves, including neurons and glial cells.
Bones are discrete organs made up of bone tissue, plus a few other things. The main misconception about bones then, is that they are made up of dead tissue. This is not true, they have cells, nerves, blood vessels and pain receptors.
You have nerves throughout your entire body. Nerves send electrical signals that help you feel sensations and move your muscles. Nerves also control body functions like digesting food and maintaining your heart rate.
Detailed Solution. The correct answer is Brain. Brain organs will not feel any pain on being pricked by a needle. The brain is a painless organ.
Have you ever had that feeling of butterflies in your stomach? It's just your nerves, literally. Your gut contains a large, but often forgotten, system of nerves. Collectively called the enteric nervous system, this system in the gut contains up to five times as many neurons as the number of neurons in the spinal cord.
The brain has no nociceptors – the nerves that detect damage or threat of damage to our body and signal this to the spinal cord and brain. This has led to the belief that the brain feels no pain.
The forehead and fingertips are the most sensitive parts to pain, according to the first map created by scientists of how the ability to feel pain varies across the human body.
Without nerve cells, we wouldn't know if it's dark or light, hot or cold. We wouldn't be able to touch anything or feel if someone is touching us. We wouldn't be able to smell or taste anything and would have no idea that we have an upset stomach or that we have cut ourselves.
Your clitoris has more nerve endings than any other part of your vulva. Together, these nerves can produce a range of pleasurable sensations, depending on how your clitoris is touched and how sexually aroused you are.
Your feet contain thousands of nerve endings that provide lots of sensations to every part of your foot. All those nerve endings start way back at your spine, branching off from the sciatic nerve where it exits the lumbar (lower) spine.
The skin is innervated by primary afferent sensory nerves, postganglionic cholinergic parasympathetic nerves and postganglionic adrenergic and cholinergic sympathetic nerves.
Skin, Hair, and Nails.
What is the Brain-Gut Connection? The digestive system has its own nervous system, called the enteric nervous system. It has over 100 million nerve endings and in many ways, it can control digestion independently without your conscious awareness.
(A) The colon and rectum are innervated by two distinct spinal pathways, the lumbar splanchnic and sacral pelvic nerves.
Adipose tissue contains nerve cells and blood vessels and communicates through hormone signals with other organs throughout your body.
You'll be surprised as to how much you could lose and still live. You can still have a fairly normal life without one of your lungs, a kidney, your spleen, appendix, gall bladder, adenoids, tonsils, plus some of your lymph nodes, the fibula bones from each leg and six of your ribs.
Skin: The skin is our body's most sensitive organ.
Organs are usually transplanted because the recipient's original organs are damaged and cannot function. The brain is the only organ in the human body that cannot be transplanted.
The sciatic nerve is the longest, largest nerve in your body. Your sciatic nerve roots start in your lower back and run down the back of each leg. Sciatica is the pain or discomfort if your sciatic nerve gets compressed or pinched.
The part of the body that has the most nerve endings is probably the fingertips. Each fingertip contains approximately 3,000 nerve endings called Meissner's corpuscles, which are designed to detect light touch and vibration.
Injured nerve cells in the central nervous system typically do not regenerate. However, this part of the nervous system can reorganize in response to an injury. This is called "plasticity." Luckily, the brain has a lot of built-in redundancy.
