What body part has lobes?
What body part has lobes?
Examples of lobes
- The four main lobes of the brain. the frontal lobe.
- The three lobes of the human cerebellum. the flocculonodular lobe.
- The two lobes of the thymus.
- The two and three lobes of the lungs. Left lung: superior and inferior.
- The four lobes of the liver. Left lobe of liver.
- The renal lobes of the kidney.
What is the bottom lobe of the brain called?
Cerebellum. The Cerebellum is a cauliflower-shaped section of the brain located in the hindbrain, at the bottom rear of the head, directly behind the pons. The cerebellum is a complex system mostly dedicated to the intricate coordination of voluntary movement, including walking and balance.
What is a lobe in the lung?
As the name implies, this lobe is located between the upper and lower (also called the superior and inferior) lobes. Each lobe receives air from its own branch of the bronchial tree, called lobar (or secondary) bronchi. Within the lungs, these bronchi are divided into smaller tubes.
What is a lobe in medical terms?
(lobe) A portion of an organ, such as the liver, lung, breast, thyroid, or brain.
How many lobes do humans have?
Brain lobes Each side of your brain contains four lobes. The frontal lobe is important for cognitive functions and control of voluntary movement or activity.
What is the word lobe mean?
: a curved or rounded projection or division specifically : a usually somewhat rounded projection or division of a bodily organ or part.
What are the lobes of the left lung?
Each lung is divided into lobes; the right lung consists of the superior, middle, and inferior lobes, while the left lung consists of only the superior and inferior lobes.
Where are the frontal and inferior lobes of the brain?
It extends laterally over the superior surface of the brain and continues almost all the way down the lateral surface of the brain to the Sylvian fissure, the lateral cerebral sulcus. This central sulcus identifies the posterior border of the frontal lobe, and the Sylvian fissure demarcates the inferior border of the frontal lobe.
Is the inferior lobe the same size as the Superior Lobe?
Note that both lungs contain an inferior lobe, and it is roughly a similar size to the superior lobe within each lung. An oblique fissure divides the superior and inferior lobes of the lung; in the right lung a horizontal fissure also separates the middle lobe. The oblique fissure is commonly found to follow the line…
Is the parietal lobe a separate part of the brain?
At Kenhub we follow the more official terminology that is found in the classical neuroanatomy textbooks and we don’t describe this part of the brain as a separate lobe. The remainder of parietal lobe can be divided into two main regions: the superior and inferior parietal lobules, which are separated anatomically by the intraparietal sulcus.
Which is smaller the inferior lobe or the middle lobe?
The inferior lobe is the smaller of the two lung lobes and is situated below and behind the fissure and comprises almost the entire base, a large portion of the costal surface and a greater part of the posterior border. The lobe that is missing or is not present in the left lung when compared to the right lung is the middle lobe.
What is the name of the lobe of the left lung?
Instead there is a small projection of the upper lobe of the left lung which is known as lingula. Lingula means ‘little’ in Latin. It is also known as tongue of the lung because of its shape. It is further divided into two segments, upper or superior and lower or inferior. Lobes of the lungs further divide into lobules.
Where are the four lobes of the brain located?
Lobes of the Brain. The four lobes of the brain are the frontal, parietal, temporal, and occipital lobes (Figure 2). The frontal lobe is located in the forward part of the brain, extending back to a fissure known as the central sulcus.
What is the frontal lobe of the brain called?
One particularly fascinating area in the frontal lobe is called the “primary motor cortex”. This strip running along the side of the brain is in charge of voluntary movements like waving goodbye, wiggling your eyebrows, and kissing. It is an excellent example of the way that the various regions of the brain are highly specialized.
