    Transcript

    00:01 So to wrap up this topic, the brain can be divided into 4 different parts: the cerebrum, the diencephalon, the brainstem, and the cerebellum.

    00:12 The brain is protected by the cranial bones of the skull as well as the meninges and the cerebrospinal fluid that surrounds it.

    00:24 The brain is also protected from unwanted substances from the blood by 2 barriers: the blood-brain barrier as well as the blood-cerebrospinal fluid barrier.

    00:37 The cerebrospinal fluid is important for the brain because it protects as well as nourishes the brain.

    00:46 The cerebrospinal fluid is synthesized in the ventricles of the brain and circulated through both the brain and the spinal cord before being returned to the venous blood.

    00:58 Extending from the brain, we have 12 cranial nerves and each of these can contain either sensory, motor nerves, or both.

    01:10 Physiologically, the brain is responsible for many things such as maintaining homeostasis as well as different parts of the brain being responsible for sensory functions, motor functions, as well as the more complex integrative functions like personality that occur in the body.

    01:34 And this concludes our lecture on the brain and the cranial nerves. Thank you for listening.
