Diencephalon: forms central core of forebrain, surrounded by cerebral hemispheres. Made of 3 paired structures: 1) thalamus, hypothalamus, and epithalamus. Thalamus: egg-shaped (known as the inner room) has midline connection called interthalamic adhesion ***EVERY part of the brain that communicated with the cerebral cortex must relay its signals through a nucleus of the thalamus. Hypothalamus:…
Hormones: chemicals released by cells that affect cells in other parts of the body Endocrine Hormones: chemicals secreted by endocrine glands directly to the blood Exocrine glands secret substances through ducts, where as endocrine glands secret directly into the blood The nervous system enables the body to adjust quickly to the environment; the endocrine system…
Scores on neuropsychological tests show amount of damage done to person Destruction and Stimulation test: can destroy parts of the brain to see effect or stimulate nerves with electrodes (Dr. Penfield- famous neuroscientists) – mapped motor and sensory areas Broca’s aphasia: could understand, but not speak Dorsal Stream: action (D.A) Ventral Stream: perception (V.P) Single-…
Thermoregulation is the maintenance of body temperature within a range that enables cells to function efficiently. Mammals, including humans, are endotherms, able to maintain a constant body temperature regardless of our surroundings. The hypothalamus acts as your body’s “thermostat”, detecting changes in body temperature and sending out messages to help restore the normal body temperature.…
Function: ▪ synthesize and release hormones permitting them to act in concert and respond to changes in the body and maintain stability (homeostasis) ▪ Example organs – thyroid, pancreas (islets of Langerhans), adrenal glands, pituitary gland Tools: – hormones * chemicals released by cells in one part of the body that affect cells in other…
