BIOS 252 Week 4 Nervous
System-Brain, Cranial
nerves, and ANS With
expert solutions
Learning Objectives:
• Distinguish the parts of the brain based on location, anatomical
landmarks, and function
• Identify the 3 meninges and their relationship to the blood brain
barrier and cerebrospinal fluid.
• Name the 12 cranial nerves and identify their functions
• Distinguish between the sympathetic and parasympathetic divisions
of the autonomic nervous system.
Introduction: The brain is the control center of the nervous system and
along with the spinal cord, forms the central nervous system. It is protected
by the cranial cavity and can be divided into 4 main parts: the brainstem,
cerebellum, diencephalon, and cerebrum. It is covered by protective
meninges and contains cavities/sinuses that are filled with cerebrospinal
fluid.
Although the brain mainly communicates with the body through the spinal
cord, it also uses 12 cranial nerves that arise directly from the nuclei in the
brain. These are considered part of the peripheral nervous system and they
serve the head and neck region. They are sensory, motor, or mixed nerves.
The autonomic nervous system is part of the peripheral nervous system
that subconsciously maintains, monitors, and controls internal functions

such as heart rate, blood vessel diameter, smooth muscle, and secretion of
glands.
Let’s put that brain to work and explore these amazing parts of the nervous
system!
Assignment:
Part 1 Complete the following activities on Anatomy.TV Nervous System:
Brain, Meninges and CSF, Cranial nerves, and Autonomic nervous
system.
To access Anatomy.TV: Resources tab>Library>Library Resources-
Database AZ>Anatomy.TV>Titles(default tab): Choose Nervous
System>choose assigned sections
You will then work through the material and activities by scrolling down
on the right. This will allow you to see and work through all activities for
that section.
Have the lab report near while working through the lab so you can record data.
Part 2 Complete the lab report.
