Emotions - The generation and experience of emotions depend on many brain structures, including the amygdala, hippocampus, and parts of the thalamus. • these structures border the brainstem in mammals and are therefore called the limbic system (from the Latin limbus, …
For the following brain regions, list each one’s principle functional role: cerebrum, cerebellum, medulla, hypothalamus, thalamus. The large part of the brain that occupies most of the space …
Experts still have a lot of questions about the brain’s role in a range of emotions, but they’ve pinpointed the origins of some common ones, including fear, anger, happiness, and love.
Overview. The brain is a very complex organ. It controls and coordinates everything from the movement of your fingers to your heart rate. The brain also plays a crucial role in how you control and process your emotions. Experts still have a lot of questions about the brain’s role in a range of emotions, but they’ve pinpointed the origins ...
Scientists haven’t reached an agreement about the full list of structures that make up the limbic system, but the following structures are generally accepted as part of the group: 1 Hypothalamus. In addition to controlling emotional responses, the hypothalamus is also involved in sexual responses, hormone release, and regulating body temperature. 2 Hippocampus. The hippocampus helps preserve and retrieve memories. It also plays a role in how you understand the spatial dimensions of your environment. 3 Amygdala. The amygdala helps coordinate responses to things in your environment, especially those that trigger an emotional response. This structure plays an important role in fear and anger. 4 Limbic cortex. This part contains two structures, the cingulate gyrus and the parahippocampal gyrus. Together, they impact mood, motivation, and judgement.
When the amygdala stimulates the hypothalamus, it initiates the fight-or-flight response. The hypothalamus sends signals to the adrenal glands to produce hormones, such as adrenaline and cortisol. As these hormones enter the bloodstream, you might notice some physical changes, such as an increase in: heart rate.
Amygdala. The amygdala helps coordinate responses to things in your environment, especially those that trigger an emotional response. This structure plays an important role in fear and anger.
Anger starts with the amygdala stimulating the hypothalamus, much like in the fear response. In addition, parts of the prefrontal cortex may also play a role in anger. People with damage to this area often have trouble controlling their emotions, especially anger and aggression. Parts of the prefrontal cortex of the brain may also contribute to ...
From a biological standpoint, fear is a very important emotion. It helps you respond appropriately to threatening situations that could harm you.

Thalamus: a coordinating center of the brain that routes sensory inputs to areas of the cerebrum devoted to generating motor responses.
Cerebrum: a large, bi-hemispheric region of the vertebrate brain that in humans functions in learning, voluntary movement, and sensory interpretation.
A neuron is a specialized cell that consists of three regions structurally. What are they?
Medulla: portion of the brain closest to the spinal cord; functions in control of involuntary processes such as heart rate and breathing intensity. Hypothalmus: control center in forebrain that regulates body temperature and responses to hunger and thirst; generates pituitary hormones.
Neither B lymphocytes nor T lymphocytes are able by themselves to respond to foreign antigen. To undergo further division, they must at some point receive another signal to proliferate (divide). They get this signal from what type of cells? See Figures 10.17, 10.18)
