LS Brain
PLTW MD Section 2.4
| Term | Definition |
|---|---|
| Frontal Lobe (Cerebrum) | Carries out higher mental processes such as thinking, decision making, and planning |
| Parietal Lobe (Cerebrum) | Processes sensory information that had to do with taste, temperature, and touch |
| Occipital Lobe (Cerebrum) | Responsible for processing visual information from the eyes |
| Temporal Lobe (Cerebrum) | Responsible for processing auditory information from the ears (hearing) |
| Brain Stem | Carries out and regulates life sustaining functions such as breathing, swallowing and heart rate |
| Cerebrum | The largest part of the human brain, associated with higher brain function such as thought and action. |
| Cerebellum | Coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity. |
| Brain Stem | Controls the flow of messages between the brain and the rest of the body, and it also controls basic body functions such as breathing, swallowing, heart rate, blood pressure, consciousness, and whether one is awake or sleepy. |
| Amygdalae | Emotional processing, including the ability to recognize certain facial emotions (especially fear), and play a role in the formation of emotional memories. |
| Hippocampus | Formation of new long-term memories, especially personal information and learn new facts: declarative (remembering facts), episodic (remembering past personal events) and relational (the ability to make associations between information). |
| Hypothallamus | Responsible for controlling hunger, thirst, sleep and body temperature through the release of hormones, in conjunction with the pituitary gland. |
| Pituitary Gland | The primary hormone secreting structure in the brain. In conjunction with the hypothalamus, it is responsible for controlling hunger, thirst, sleep, and body temperature. |
| Midbrain | Part of the brainstem, and plays a primary role in sleep, arousal and temperature regulation, and motor control. |
| Thalamus | The main relay through which incoming sensory information passes before being sent to the cerebral cortex, and also helps regulate alertness and sleep. |
| Basal Ganglia | Involved in initiating voluntary movements, and are involved in the ability to learn particular sequences of movement (such as those needed to type). |
| Pons | Part of the brainstem. Plays a role in controlling sleep, respiratory function, hearing, as well as motor control and touch in the region of the face. |
| Medulla Oblongata | Part of the brainstem. Plays a major role in controlling cardiac and respiratory function. |
| Corpus Collasum | Connects the right and left hemispheres of the brain |
| Pineal Gland | A small, pea-shaped gland in the brain which produces and regulates some hormones, including melatonin. Melatonin is best known for the role it plays in regulating sleep patterns. |
| Central Nervous System | The brain and spinal cord |
| Peripheral Nervous System | Everything outside the brain and spinal cord |
| Somatosensory | Relating to a sensation (such as pressure, pain, or warmth) which can occur anywhere in the body; in contrast to one localized at a sense organ (such as sight, balance, or taste) |
| Afferent | Carry electrical impulses from the body to the spinal cord |
| Efferent | Carry electrical impulse from the spinal cord to the body (ex. Muscles) |
