What is the main function of the myelencephalon?
The myelencephalon Medulla oblongata – Located between the pons and brain stem, the medulla is responsible for basic life support functions like respiration and heart rate.
What is the main component of the myelencephalon?
The myelencephalon consists of the medulla oblongata, which forms the brain posterior to the metencephalon and connects to the spinal cord (Figures 7.76 and 7.77). The ventral fissure is the median ventral groove of the medulla. To either side are narrow longitudinal bands termed pyramids.
What is the purpose of the hindbrain?
The hindbrain coordinates functions that are fundamental to survival, including respiratory rhythm, motor activity, sleep, and wakefulness. It is one of the three major developmental divisions of the brain; the other two are the midbrain and forebrain.
What is the meaning of Medular?
1a : of or relating to the medulla of any body part or organ. b : containing, consisting of, or resembling bone marrow. c : of or relating to the medulla oblongata or the spinal cord.
What is the optical lobe?
The occipital lobes sit at the back of the head and are responsible for visual perception, including colour, form and motion. Damage to the occipital lobe can include: Difficulty with locating objects in environment.
What is cerebrum and cerebellum?
The cerebrum and Cerebellum are the two parts of the human brain or central nervous system that plays an essential role in our life. The cerebrum is the largest part of the brain whereas the cerebellum is a much smaller part of the brain.
What does the myelencephalon develop into?
The myelencephalon, the most caudal subdivision of the rhombencephalon, develops into the medulla oblongata of the adult brain (Figure 3). It is in many respects a transitional structure between the brain and spinal cord, and the parallels between its functional organization and that of the spinal cord are readily apparent (Figure 4).
What is the posterior myelencephalon?
myelencephalon The posterior part of the hindbrain (rhombencephalon) in the embryo, which differentiates into the medulla oblongata, the caudal end of the fourth ventricle and cranial nerves 8 to 12. Segen’s Medical Dictionary. © 2012 Farlex, Inc.
What is the difference between myelencephalon and neural structure?
myelencephalon – the posterior part of the hindbrain in developing vertebrates; forms the medulla oblongata in adults. neural structure – a structure that is part of the nervous system.
What is the ventral fissure of the myelencephalon?
The myelencephalon consists of the medulla oblongata, which forms the brain posterior to the metencephalon and connects to the spinal cord ( Figures 7.76 and 7.77 ). The ventral fissure is the median ventral groove of the medulla.
