Damage to Temporal Lobes can lead to… • disturbance of language comprehension • altered sexual behavior (increase or decrease sex drive) • Difficulty in recognizing faces ( Prosopagnosia video clip ) (Clip 2) • Difficulty in understanding spoken words ( Wernicke's Aphasia clip) • Short-term memory loss • Interference with long-term memory • Right lobe damage can cause persistent talking • Increased aggressive behavior

Damage to Temporal Lobes can lead to…
• disturbance of language comprehension • altered sexual behavior (increase or decrease sex drive)• Difficulty in recognizing faces (Prosopagnosia video clip) (Clip 2)• Difficulty in understanding spoken words (Wernicke's Aphasia
clip)• Short-term memory loss• Interference with long-term memory • Right lobe damage can cause persistent talking • Increased aggressive behavior

Fill in the boxes with the terms:autonomic, CNS, parasympathetic, PNS, somatic, sympathetic
II. The peripheral nervous system (PNS)
What is the PNS? The nerves that run throughout your body connecting your sensory organs (skin, eyes, ears, tongue, nose) & internal organs to your brain and spine (CNS)
1. Sensory/afferent nerves: The body’s organs use these to send sensations to the brain
e.g. afferent nerves on tongue (taste buds) sense flavor, afferent nerves on skin senses touch, afferent nerves on in ears sense sound waves, etc.
2. Receptors: the part of the sensory organ that receives information (sound, light, heat, pressure, flavor, smell) from environment (auditory receptors, olfactory, visual, kinesthetic, taste buds)
3. Motor/efferent nerves: carry outgoing signals from the CNS to the muscles, skin, and glands of body triggering movement
4. Interneurons: CNS neurons in spine and brain that receive incoming from sensory receptors so brain can process/perceive and so brain can send outgoing information to motor neurons

• 2 parts: sympathetic and parasympathetic – Sympathetic: Drives
flight or fight response during stressful/strenuous events
• Speeds up heart• directs blood flow to
muscles that need most oxygen
• suspends digestion• adrenal glands
release epinephrine (AKA adrenalin)
– Parasympathetic: relaxation, returns systems to normal speed (homeostasis) after shock, stress
Autonomic system
mnemonic: para means to stop in Spanish!parachute slows your fall
III. Endocrine SystemIII. Endocrine System• What? Network of glands
located in brain and body • Function? Sends hormone
chemical messages through blood stream to body’s organs to control:
– metabolism– growth– sexual development– flight or fight response
• In females: ovulation, menstruation, and lactation
• In males: sperm production, deepening of voice, growth of sex organs

III. Endocrine System (cont)III. Endocrine System (cont)• Thyroid gland produces hormone that
regulates metabolism (how quickly/slowly one digests food)– Not enough hormone (hypothyroidism)=
sluggish, no appetite– Too much hormone
(hyperthyroidism)=eat a lot, hyperactive• Adrenal glands release cortisol & epinephrine
(adrenalin) when person frightened or angry• Hypothalamus (part of limbic system)
coordinates communication between endocrine and nervous systems
