What is the hindbrain mainly responsible for?
The hindbrain coordinates functions that are fundamental to survival, including respiratory rhythm, motor activity, sleep, and wakefulness. It is one of the three major developmental divisions of the brain; the other two are the midbrain and forebrain.
Where is the hindbrain located and what functions there?
The hindbrain is located at the back of the head and looks like an extension of the spinal cord. It contains the medulla, pons, and cerebellum. The medulla controls the automatic processes of the autonomic nervous system, such as breathing, blood pressure, and heart rate.
What is the function of the hindbrain quizlet?
The hindbrain is often referred to as the 'lower brain'. It mainly supports bodily functions and it is the link between the spinal cord and the brain. It is important for movement and balance. It is comprised of the medulla, pons, cerebellum and part of reticular formation.
What is the function of hindbrain and midbrain?
The midbrain plays a role in motor movement and audio/visual processing. The hindbrain is involved with autonomic functions such as respiratory rhythms and sleep.
What types of functions do the hindbrain and midbrain govern?
The midbrain and the hindbrain together make up the brainstem. The midbrain or mesencephalon, is the portion of the brainstem that connects the hindbrain and the forebrain. This region of the brain is involved in auditory and visual responses as well as motor function.
What is hindbrain in psychology?
The Hindbrain, also formally known as the rhombencephalon, is the portion of the brain that contains the pons, cerebellum and medulla, and is responsible for regulating basic human functions.
What types of functions do the hindbrain and the midbrain govern?
The midbrain and the hindbrain together make up the brainstem. The midbrain or mesencephalon, is the portion of the brainstem that connects the hindbrain and the forebrain. This region of the brain is involved in auditory and visual responses as well as motor function.
What are the different structures of the hindbrain and what do they do?
The hindbrain is composed of the medulla, the pons, and the cerebellum. The medulla lies next to the spinal cord and controls functions outside conscious control, such as breathing and blood flow. In other words, the medulla controls essential functions.
What is hindbrain and forebrain?
Forebrain, midbrain and hindbrain are the three areas of the brain, constituting different parts of the brain. Forebrain comprises cerebrum, thalamus and hypothalamus. Midbrain is located between the thalamus of the forebrain and pons of the hindbrain. Hindbrain comprises pons, cerebellum and medulla.
Which structure of the hindbrain controls sleep and dreaming?
The brain stem, at the base of the brain, communicates with the hypothalamus to control the transitions between wake and sleep. (The brain stem includes structures called the pons, medulla, and midbrain.)
Which part of the hindbrain is involved in sleep and arousal?
The reticular formation The reticular formation is centered in the midbrain, but it actually extends up into the forebrain and down into the hindbrain. The reticular formation is important in regulating the sleep/wake cycle, arousal, alertness, and motor activity.
What part of the hindbrain is involved in sleep and arousal?
The reticular formation is centered in the midbrain, but it actually extends up into the forebrain and down into the hindbrain. The reticular formation is important in regulating the sleep/wake cycle, arousal, alertness, and motor activity.
Which part of brain is responsible for learning?
Hippocampus. A curved seahorse-shaped organ on the underside of each temporal lobe, the hippocampus is part of a larger structure called the hippocampal formation. It supports memory, learning, navigation and perception of space.
What part of the brain controls balance and walking?
The cerebellum The cerebellum is located behind the brain stem. While the frontal lobe controls movement, the cerebellum “fine-tunes” this movement. This area of the brain is responsible for fine motor movement, balance, and the brain's ability to determine limb position.
What part of brain controls sleep?
hypothalamus The hypothalamus, a peanut-sized structure deep inside the brain, contains groups of nerve cells that act as control centers affecting sleep and arousal.
Which part of brain is responsible for emotions?
The limbic system is a group of interconnected structures located deep within the brain. It's the part of the brain that's responsible for behavioral and emotional responses.
What part of the brain controls memory and concentration?
The prefrontal cortex The prefrontal cortex plays an important part in memory, intelligence, concentration, temper and personality.
What part of the brain keeps you breathing?
The brain stem The brain stem sits beneath your cerebrum in front of your cerebellum. It connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate and blood pressure.
What does it mean when you wake up at 3am?
If you wake up at 3 a.m. or another time and can't fall right back asleep, it may be for several reasons. These include lighter sleep cycles, stress, or underlying health conditions. Your 3 a.m. awakenings may occur infrequently and be nothing serious, but regular nights like this could be a sign of insomnia.

Another belief is that you are probably having a hard time in life and there are some disappointments marring your peace. You could also be in depression so take care of your health and wear light clothes when sleeping.
What part of the brain controls depression?
The main subcortical limbic brain regions implicated in depression are the amygdala, hippocampus, and the dorsomedial thalamus. Both structural and functional abnormalities in these areas have been found in depression.
What part of the brain controls anxiety?
The amygdala is responsible for the expression of fear and aggression as well as species-specific defensive behavior, and it plays a role in the formation and retrieval of emotional and fear-related memories.
What part of the brain controls motivation and emotion?
Limbic cortex Limbic cortex. This part contains two structures, the cingulate gyrus and the parahippocampal gyrus. Together, they impact mood, motivation, and judgement.
What part of the brain holds memory?
Hippocampus. The hippocampus, located in the brain's temporal lobe, is where episodic memories are formed and indexed for later access.
What part of the brain helps you walk?
Cerebellum Cerebellum. The cerebellum sits at the back of the brain and controls your sense of balance. This allows you to stand up, walk in a straight line, and know if you are standing up or sitting down.
What organ is active at 4am?
lungs The hours between 3am and 5am are governed by the lung meridian. Emotionally it is associated with grief and physically with the muscles around your lungs. The hours between 5am and 7am are governed by large intestine.

What part of brain causes anxiety?
There are two parts of the brain that are thought to be key players in the production and processing of anxiety – the amygdala and the hippocampus.
What part of the brain causes anger?
When an angry feeling coincides with aggressive or hostile behavior, it also activates the amygdala, an almond–shaped part of the brain associated with emotions, particularly fear, anxiety, and anger.
