What’s the smallest organ in the body?
What’s the smallest organ in the human body.
You’ll find the pineal gland near the center of the brain, in a groove between the hemispheres.
It’s not an organ like those in the abdominal cavity..
What protects the brain from things entering?
The brain and the spinal cord are protected by bone: the brain by the bones of the skull, and the spinal cord by a set of ring-shaped bones called vertebrae. They’re both cushioned by layers of membranes called meninges and a special fluid called cerebrospinal fluid.
What part of the body is the quickest to heal?
corneaThe cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is the fastest healing tissue in the human body, thus, most corneal abrasions will heal within 24-36 hours.
What is the most superior portion of the brain?

Which is the smallest part of brain?
midbrainThe midbrain is often considered the smallest region of the brain. It acts as a sort of relay station for auditory and visual information. The midbrain controls many important functions such as the visual and auditory systems as well as eye movement.
What is oblongata?
The medulla oblongata or simply medulla is a long stem-like structure which makes up part of the brainstem. It is anterior and partially inferior to the cerebellum. It is a cone-shaped neuronal mass responsible for autonomic (involuntary) functions ranging from vomiting to sneezing.
What part of the brain controls emotions?
limbic systemWhere do emotions come from? The limbic system is a group of interconnected structures located deep within the brain. It’s the part of the brain that’s responsible for behavioral and emotional responses.
What is the biggest bone of human body?
thighboneYour femur, or thighbone, is the largest bone in your body. The head of your femur fits into your hip socket and the bottom end connects to your knee. The two bones beneath your knee that make up your shin are your tibia and fibula. Your upper and lower leg are connected by a hinge joint.
What is the second strongest muscle in the human body?
So here are the top five strongest muscles in the body based on these different ways to measure strength:Heart. The heart, which consists of cardiac muscle, is said to be the hardest working muscle in the body. … Masseter. … Soleus. … Gluteus Maximus. … Uterus.
What is the uppermost layer of the brain?
The cortex comprises the uppermost layer of the brain and is considered the highest center of the brain’s function.
What is the strongest muscle in the human body?
masseterThe strongest muscle based on its weight is the masseter. With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars. The uterus sits in the lower pelvic region.
What are the 3 types of the brain?
The brain can be divided into three basic units: the forebrain, the midbrain, and the hindbrain. The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum (1). The hindbrain controls the body’s vital functions such as respiration and heart rate.
Does sleeping heal wounds faster?
A good night’s sleep can improve your mood, help you stay alert and boost your memory. Now data show that getting enough Z’s might also get your cuts to heal more promptly. In fact, sleep was more important than good nutrition in speeding wound healing. This wasn’t what scientists had expected to see.
Which is the hardest substance in our body?
Tooth enamelTooth enamel is the hardest substance in the body. The shiny, white enamel that covers your teeth is even stronger than bone. This resilient surface is 96 percent mineral, the highest percentage of any tissue in your body – making it durable and damage-resistant.

What is the largest portion of your brain?
cerebrumThe largest part of the brain, the cerebrum has two hemispheres (or halves). The cerebrum controls voluntary movement, speech, intelligence, memory, emotion, and sensory processing.
What is the biggest part of the body?
SkinBody organs aren’t all internal like the brain or the heart. There’s one we wear on the outside. Skin is our largest organ—adults carry some 8 pounds (3.6 kilograms) and 22 square feet (2 square meters) of it.
What’s the slowest healing body part?
Cartilage Healing Considerations Cartilage is avascular, meaning that it has no blood supply. The lack of blood circulation in cartilage means that it is a very slow-healing type of tissue. Nutrition to cartilage is maintained by fluid in the joints, which lubricates the tissue.
Is cerebellum A?
The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity.
Which is the second largest part of the brain?
cerebellumThe cerebellum is the second largest part of the brain.
What injuries take the longest to heal?
Bone fractures and minor muscle injuries: these typically heal a lot faster, from weeks to months. Tendon or ligament: these take longer, from months to a year.
