Parts of the brain
Question | Answer |
---|---|
Medula | Regulates respiration, heart rate, and blood pressure (Central Core) |
Pons | Regulates sleep-wake cycles (Central Core) |
Cerebellum | Regulates reflexes and balance coordinates movement (Central Core) |
Thalamus | Major sensory relay center (Central Core) |
Hypothalamus | Emotion and motivation; stress reactions and eating and drinking; sexual activity (Central Core) |
Hippocampus | Essential role in forming new memories (Limbic system) |
Amygdala | Governs emotions related to self-persevation |
Temporal Lobe | Smelling, Hearing, balance and equilibrium; Emotion and motivation; Language comprehension and complex visual processing |
Occipital lobe | Receives and processes visual information |
Parietal lobe | Sensory projection and association areas; Visual/spacial abilities receives bulk of sensory information |
Frontal Lobe | Voluntary action and problem-solving tasks "control center" for the brain parts. Organizes information |
Central Fissure | separates primary somatosensory cortex from the primary motor cortex |
Primary motor cortex | (Frontal Lobe) sends messages to muscles and glands; key role in voluntary movement |
Primary somatosensory cortex | Registers sensory messages from the entire body |
Olfactory bulb | Responsible for sense of smell |
Lateral sulcus | seperates parietal and temporal lobes |
Pituitary gland | Produces Growth hormone and regulates endocrine functions. |
Pineal Gland | Causes sleepiness, Secretes hormone Melatonin; converts nervous system signals to endocrine signals |
Corpus Callosum | connects left and right hemispheres |
Cingulate gyrus | Regulates aggressive behavior, Emotional responses to pain, and Coordinates sensory input with emotions |
midbrain | where pain is registered, important in hearing and sight |
Reticular Formation | network of neurons in hindbrain, midbrain, and part of forebrain; to alert and arouse higher parts of the brain |
neurogenesis | growth of new neurons |
CNS | central nervous contains brain and spinal coard (90% of neurons) |
PNS | Peripheral nervous; connects CNS to rest of body |
Hindbrain | area containing medulla, pons, and cerebellum |
