The Midbrain approximately ____long forms a major part of the _______ Is the most _________ portion of the brain stem

The Midbrain The midbrain helps coordinate ___________________ information with simple _____________ What does that mean?  Sensory information is anything you feel using one of your five basic senses.  If someone hocks a lugi  at your head and you watch the goober travel through the air and track the incoming with your eyes at it races at your head, you are using your vision and eye and neck muscles together.  That is what I mean by sensory information with simple movements.  Just reading this text now, you are using your midbrain to keep your eyes and head moving.

The Midbrain The key part of the midbrain for psychological purposes is the ___________________ It controls ________________ Not sexual arousal, but actual “____________" arousal".  If you were in a deep sleep and I stimulated your Reticular Formation you would instantly wake up and not be tired at all.  If I lesioned (cut out) your Reticular Formation, you would fall into a __________ from which you would never wake.

Damage to the Midbrain If a boxer is knocked out, part of the reason lies in the mid-brain. If a person is unconscious due to a damaged midbrain, he might go into a coma because the forebrain can not be aroused

The Hindbrain The area of the brain comprising the _______, _________ and _____________The hindbrain functions collectively to co-ordinate various functions

The Pons The word “pons” means _____________ . It functions as a bridge to interconnect messages between the _______________and brain If someone has a serious _________ disorder, it may involve the pons as the pons makes the ______________ involved in sleep Also important in controlling ____________ . In Latin, pons makes the chemicals involved in sleep (Purves et al., 2004). The brain stem is located beneath the limbic system. It is responsible for vital life functions such as breathing, heartbeat, and blood pressure. The brain stem is made of the midbrain, pons, and medulla.

The Medulla Injury to the medulla results in _______________ . The medulla, which is located at the top of the spinal cord, includes a group of cells that control vital reflexes, such as respiration, heart rate, and blood pressure. control our ____________blood pressure and ___________.  located directing above our spinal cord if you get hurt in the Medulla you should just pack it in. Injury to the medulla results in _______________ .

The Medulla . The medulla, which is located at the top of the spinal cord, includes a group of cells that control vital reflexes, such as respiration, heart rate, and blood pressure. If someone dies of a drug overdose, the cause of death probably involved the medulla Large amounts of alcohol, heroin, or other depressant drugs suppress the functions of cells in the medulla and cause death by stopping breathing. he primary role of the pons is to serve as a bridge between various parts of the nervous system, including the cerebellum and cerebrum. As part of the brainstem, a section of the lower pons stimulates and controls the intensity of breathing, while a section of the upper pons decreases the depth and frequency of breaths. The pons is also associated with the control of sleep cycles, and controls respiration and reflexes.

Cerebellum Found at the at the back of your head under the cerebrum Means “_____________” The Cerebellum helps us coordinate our___________and fine __________ movements.  Often takes over learned activities- like riding a bike Of the brain’s three parts, the forebrain is the largest, most evolved, and most responsible for an enormous range of personal, social, emotional, and cognitive behaviors. For those reasons, we’ll examine the forebrain in more detail.

Cerebellum A person suspected of drunken driving may fail the test of rapidly touching a finger to the nose because of alcohol’s effects on the cerebellum. Because alcohol is a depressant drug and interferes with the functions of the cerebellum, an intoxicated person would experience decreased coordination and have difficulty rapidly touching a finger to the nose, which is one of the tests for being drunk. Of the brain’s three parts, the forebrain is the largest, most evolved, and most responsible for an enormous range of personal, social, emotional, and cognitive behaviors. For those reasons, we’ll examine the forebrain in more detail.
