Doreen Pang Mrs. Trainor AP Psychology 13 October 2016 Module 5-2 The Cerebral Cortex Cerebral Cortex an intricate covering of interconnected neural cells that forms a thin surface layer on the cerebral hemispheres Expansion of cerebral cortex tight genetic controls relaxes organism?s adaptability increases Frogs and other amphibians have a small cortex operates extensively on programmed genetics instructions The larger cortex of mammals offers: increased capacities for learning and thinking allows them to be more adaptable Structure of the Cortex 80% of brain?s weight = the ballooning left and right hemispheres covered w/ axons connection between brain?s surface and its other regions Cerebral cortex brain?s hemisphere contains 20-23 billion nerve cells

Doreen Pang Mrs. Trainor AP Psychology 12 October 2016 Module 5-1: The Brain The Tools of Discovery Lesion (Tissue destruction) destroy EEG the electrodes on head Usually used for sleeping waves PET looks at radioactive glucose Looks at molecular cellular structure allows for us to detect disease early MRI magnetic fields and radio waves to look at soft tissue Brainstem Oldest structure Responsible for older structures Base is Medulla controls heartbeat and breathing damage=death Pons Above the medulla helps coordinate movement Reticular Formation (Reticular Activating System) Runs all the way down the brainstem think nylons controlling arousal damage=coma Thalamus on top of brainstem directs messages to the sensory areas (except smell) Cerebellum ?little brain?

Doreen Pang Mrs. Trainor AP Psychology 11 October 2016 Module 4-4 The Endocrine System Our body has two communications system: Endocrine and Neural Endocrine System Travels through blood interconnected with the nervous system secrete glands chemical messages Hormones Chemical messengers that circulate in the blood Hormones Originates in one tissue travels through blood stream affects other tissues: like the brain influences: sex food aggression Some Hormones are chemically the same as neurotransmitters those chem. messengers: diffuse across synapse excite/inhibit an adjacent neuron Endocrine/nervous systems are kindred The 2 differences are: Slower Effects lasts longer both secrete molecules that activate receptors elsewhere Endocrine is slower than nervous system

Vesicle

Endomembrane system 4/7/16 Proteins synthesized in the ER enter the endomembrane system Comprises a transport system whereby material flows between the ER, Golgi, endosomes, lysosomes, and the plasma membrane REMEMBER: Rough ER is involved in biosynthesis and processing of proteins Smooth ER is involved in drug detoxification, carbohydrate metabolism, steroid biosynthesis Network of small tubes Both water-soluble and transmembrane proteins are co-translated: Soluble ? completely translocated across the ER membrane into the lumen Default pathway = SECRETION Transmembrane ? partly translocated and will reside in the membrane Default pathway = PLASMA MEMBRANE Most proteins that enter the endomembrane system get glycosylated cytosolic proteins are generally not glycosylated

3/22/16 Cytoskeleton - a system of protein filaments that extend through cytosol The cytoskeleton helps support the large volume of cytosol inside a cell Most prominent in eukaryotic cells However, unlike our static skeleton, the cytoskeleton is dynamic Cytoskeletal filaments are made of noncovalently-linked subunits *allows for rapid assembly and disassembly* Filaments can disassemble and reassemble in different locations in cell Cytoskeleton Functions maintains cell SHAPE & RIGIDITY A framework connecting the plasma membrane to the organelles CELLULAR MOVEMENT MOTILITY: whole cell i.e. amoeba or sperm ? cilia/flagella intracellular structures - chromosomes, vesicles CONTRACTILITY - movement involving contraction of a cell muscle - tissue, cleavage furrow.

Not living organisms but incapable of reproducing on their own Can grow and develop Require energy - metabolism Response to the environment Maintain homeostasis Contains genetic information (DNA or RNA) Composed of cells Cells are the fundamental unit of life. Invention of the light microscope led to the discovery of cells Robert Hooke Shortened telescope Many flaws, difficult to see Oil lamp with flask of water to illuminate specimen Examined cork - coined term cell Remains of cell walls after death Theodore Schwann All different species of animals were composed of cells Mathias Schleiden All different species of plants were composed of cells

AP BIOLOGY DIGESTION/HOMEOSTASIS 75 Name: Pledge: 1. Distinguish between an incomplete and complete DS. Give an example of an organism for each. (6) Incomplete systems have one ?pouch like? cavity which serves as both the mouth and anus. There is one opening for mouth and anus. Organisms: hydra, flat worm, invertebrates With a complete system the digestive tube has two openings for the mouth and anus. As well, other sites for the different processes of digestion like the stomach and the bowels. Organisms: all other phyla: humans, animals, 2. Why are some proteolytic enzymes produced in an inactive form? (4)

By: Chlo? Durfee Sydney Modder Ramya Ramesh Megumi Sharma Chase Damis The Respiratory System Larynx (Voice Box) Connects pharynx to trachea Provides airway Prevents food from entering respiratory tract Produces sound Pharynx (throat) Provides passageway for respiratory and digestive tracts Tube like structure that connects nasal and oral cavities to larynx Coordinates breathing and swallowing while eating Larynx/Pharynx Larynx/Pharynx Epiglottis Blocks food and liquids from entering the trachea Spoon-like structure Epiglottis Lungs Pair of spongy, air-filled organs. Located on either side of thorax. Covered by thin tissue called pleura. Pull in oxygen and absorbs it into linings of lungs. Pushes oxygen into chambers of the heart so oxygen travels throughout the body.
