The five major divisions of the brain are the
telencephalon, the diencephalon, the mesencephalon, the metencephalon, and the
myelencephalon. The telencephalon, which is the human brain's largest division,
is responsible for mediating the most complex functions of the brain (Pinel,
2009). It is responsible for initiating voluntary movement, interprets sensory
input, and mediates complex cognitive processes such as speaking, problem
solving, and learning (Pinel, 2009). The diencephalon is a divison of the human
brain, which is composed of the thalamus and the hypothalamus. The thalamus has
sensory relay nuclei, which receive signals from sensory receptors, then
processes the signals, and transmits those signals to the designated areas of
the sensory cortex (Pinel, 2009). The hypothalamus plays a role in regulating
several motivated behaviors by regulating the release of hormones from the
pituitary gland (Pinel, 2009).
The
mesencephalon is a division that is comprised of two divisions, which are the
tectum and the tegmentum. The tectum is composed of the inferior colliculi,
which have an auditory function, and the superior colliculi, which have a
visual function (Pinel, 2009). The tegmentum contains three structures, which
are the periaqueductal gray, the substantia nigra, and the red nucleus. The periaqueductal
gray has a role in mediating the analgesic (pain-reducing) effects of opiate
drugs (Pinel, 2009). The substantia nigra and the red nucleus are important
components of the sensorimotor system (Pinel, 2009). The metencephalon is a
division that has two major divisions, which are the pons and the cerebellum.
The cerebellum is a sensorimotor structure, which function is sensorimotor
control. The myelencephalon, also referred to as the medulla, is the most
posterior division of the brain (Pinel, 2009). It plays a role in arousal and
is is responsible for functions such as
sleep, movement, attention, the maintenance of muscle tone, and various
cardiac, circulatory, and respiratory reflexes (Pinel, 2009).

STEVEN - PLEASE REMOVE THESE POSTS FROM YOUR BLOG. Students are using this site to try and cheat REPEATEDLY. I cannot even count how many times your answers are getting used in my course. And yes, I know you were a student in my course because you have answers on here to specific questions that I ask. Ultimately, you are assisting students in using short cuts to pass college courses. Please remove all of the answers to DQs and worksheets from this blog.
ReplyDeleteWhy is this school and the instructors recycling the same questions every year?
DeleteThat is not the point. That is up to the school. The point is that he is trying to help people cheat.
DeleteKeep doing your thing Steven. - a student using this to study
ReplyDeleteHis "thing" is helping students cheat. I have given a 0 to 20+ students due to their direct copy and pasting from this website/blog. It would be very different if this was a study guide, but he posted his answers to all the Discussion Questions when he took the course, as well as his answers to actual assignments. It is promoting cheating.
