Examples of bronchopulmonary segment in the following topics:
-
- It bears apical, anterior, and posterior bronchopulmonary segments.
- It bears medial and lateral bronchopulmonary segments.
- It bears medial, lateral, superior, anterior, and posterior bronchopulmonary segments.
- The upper lobe of the left lung contains anterior and apicoposterior bronchopulmonary segments.
- It contains superior and inferior bronchopulmonary segments.
-
- The lobar bronchi (also called secondary bronchi) divide into tertiary bronchi, each of which supplies air to a different bronchopulmonary segment.
- A bronchopulmonary segment is a distinct region of the lung separated from the rest of the lung by connective tissue.
- Each bronchopulmonary segment forms a discrete functional unit in the lung that is independent of the other segments.
- This property allows a bronchopulmonary segment to be surgically removed without affecting other segments.
- There are 10 segments in the right lung and 8 to 9 segments in the left lung due to anatomical differences.
-
- Another problem can be chronic lung disease, previously called bronchopulmonary dysplasia or BPD.
-
- The path of the facial nerve can be divided into six
segments.
-
- During fetal life, the primitive gut can be divided into three segments: foregut , midgut , and hindgut .
- These terms are regularly used to describe both segments of the primitive gut and components of the definitive gut.
- In later development each segment of the gut gives rise to specific gut and gut-related structures.
-
- The muscularis is responsible for segmental contractions and peristaltic movement in the GI tract.
- The muscularis is responsible for segmental contractions and peristaltic movement in the GI tract.
- Occasionally in the large intestine (two to three times a day), there will be mass contraction of certain segments, moving a lot of feces along.
-
- During fetal life, the primitive gut can be divided into three segments: foregut, midgut, and hindgut.
- Although these terms are often used in reference to segments of the primitive gut, they are also used regularly to describe components of the definitive gut as well.
- Each segment of the gut gives rise to specific gut and gut-related structures in later development.
-
- When an axon is damaged, the distal segment undergoes Wallerian degeneration, losing its myelin sheath.
- The proximal segment can either die by apoptosis or undergo the chromatolytic reaction, which is an attempt at repair.
- When a nerve axon is severed, the end still attached to the cell body is labeled the proximal segment, while the other end is called the distal segment.
- The distal segment, however, experiences Wallerian degeneration within hours of the injury; the axons and myelin degenerate, but the endoneurium remains.
- Slower degeneration of the distal segment than that which occurs in the peripheral nervous system also contributes to the inhibitory environment; inhibitory myelin and axonal debris are not cleared away as quickly.

- The proximal segment attempts to regenerate after injury, but its growth is hindered by the environment.
-
- Uterine muscles form opposing spirals from the top of the upper segment of the uterus to its junction with the lower segment.
- During effacement, the cervix becomes incorporated into the lower segment of the uterus.
- During a contraction, these muscles shorten the upper segment, drawing upwards the lower segment in a gradual expulsive motion.
