What is meant by rhombencephalon?
rhombencephalon. / (ˌrɒmbɛnˈsɛfəˌlɒn) / noun. the part of the brain that develops from the posterior portion of the embryonic neural tube and comprises the cerebellum, pons, and the medulla oblongataNontechnical name: hindbrain Compare mesencephalon, prosencephalon.
What does the rhombencephalon gives rise to?
The rostral part of the rhombencephalon becomes the metencephalon and gives rise to the adult cerebellum and pons. Finally, the caudal part of the rhombencephalon becomes the myelencephalon and gives rise to the adult medulla.
What are the parts of the rhombencephalon?
The rhombencephalon consists of two parts: the anterior metencephalon, which later forms the pons and the cerebellum; and the posterior myelencephalon, which later gives rise to the medulla oblongata.
Is the rhombencephalon the brainstem?
The Hindbrain or Rhombencephalon The medulla, pons and mesencephalon make up the brainstem. The medulla is sometimes referred to as the bulb because it appears as an anterior expansion of the spinal cord.
What does the metencephalon turn into?
The metencephalon (see Fig. 3.2) is the embryonic portion of the hindbrain. It differentiates into the pons and cerebellum, and contains part of the fourth ventricle. Nuclei of the trigeminal nerve (CN V), abducens nerve (CN VI), facial nerve (CN VII), and vestibulocochlear nerve (CN VIII) are within the pons.
What brain vesicles comes from the diencephalon?
The prosencephalon enlarges into two new vesicles called the telencephalon and the diencephalon. The telecephalon will become the cerebrum. The diencephalon gives rise to several adult structures; two that will be important are the thalamus and the hypothalamus.
What is the most rostral part of the brain?
The cerebral hemispheres of the brain are divided into four lobes. The frontal lobes are the most rostral, located in the front of the brain and are responsible for higher level executive functions, like attention, critical thinking, and impulse control.
What does the pons do?
The pons is part of a highway-like structure between the brain and the body known as the brainstem. The brainstem is made up of three sections, and carries vital information to the body. The pons relays information about motor function, sensation, eye movement, hearing, taste, and more.
What is pons in psychology?
Pons: n. a structure on the brain stem that lies above the medulla and regulates sleep, arousal, consciousness, and sensory processes.
What is a pons?
Listen to pronunciation. (ponz) Part of the central nervous system, located at the base of the brain, between the medulla oblongata and the midbrain. It is part of the brainstem.
What is the isthmus rhombencephalon?
isthmus of rhombencephalon the narrow segment of the fetal brain, forming the plane of separation between the rhombencephalon and cerebrum.
