BIPN 100 Sensory Pathways Types of Receptors + Neurons Receptive Field, Lateral Inhibition Generator(Receptor) Potentials Tonic + Phasic Receptors Spinal Pathways, Crossing to the Opposite Side Thalamus + Somatosensory Cortex Pain Modulation Autonomic System Anatomy, CNS Centers, Pre + Post-Ganglionic Neurons Parasympathetic: Cranio-sacral Sympathetic: Thoraco-lumbar Cholinergic + Adernergic Receptors Actions on Target Cells Somatic Motor Systems Reflexes Mono + Polysynaptic, Somatic, Autonomic Spinal, Cranial, Learned, Conditioned Muscle Spindles + Golgi Tendon Organs Withdrawal Reflexes Endocrine System Hormones: Hydrophilic v. Hydrophobic Peptide/Protein, steroid, amines Coordination of Movement Hormones, Receptors +Transducers

Isotonic + Isometric Contraction Motor Units Smooth Muscle: Types of Contraction and Mechanism Cardiac Muscle Heart-Anatomy Cardiac Action Potentials Pacemaker Potentials Excitation-Contraction Coupling Action Potential-Contractile Fibers, Pacemakers Conduction System Electrocardiogram: Waves and Segments Cardiac Cycle: Diastole and Systole Changes in Volume, Pressure, Valves Pre-load After Load Electrical + Mechanical Events Heart + Aorta Cardiac Output Regulation of Heart Rate + Contractility Sensory Pathways Mechanoreceptors: respond to mechanical stimuli; touch, pressure, stretch o Hair cells: have sensitive hairs, which have ion channel Baroreceptors: respond to changes in arterial pressure Chemoreceptors: ligand-gated channels Receptors that sense pH, oxygen, and other parameters Photoreceptors: respond to light

Olfactory receptors Proprioreceptors: respond to changes in position Generator potential(receptor potential): depolarization will cause action potential to be transported into spinal cord Myelinated fibers: A and B fast fiberss, Unmyelinated fibers: C slow fibers Receptive field: area which is covered by the sensory neuron, overlap have common sensory axons Two –point discrimination: many primary sensory neurons converge onto a single secondary neurons, increase # secondary neurons increase discrimination Lateral inhibition: primary sensory neurons responds to the stimulus, excites
