Study Guide #2 Types of Synapses A(n) (electrical/chemical/voltage) synapse signals via direct transfer, or through ​gap ​ ctions, whereas a(n) (electrical/chemical/voltage) synapse signals via neurotransmitters released in the ______________ cleft. __________________- slower than an electrical synapse, and only goes in one direction. Chemical Synapse Steps: 1. Action potential reaches the ___________ ____________. 2. ________ enters the synaptic knob through ____________ gated channels and stimulates the ______________. 3. __________________ is released by (exocytosis/endocytosis). 4. __________________ binds to receptors on the post-synaptic cleft via _____________ channel 5. Channel opens. Inhibitory Synapse- ____________________________________________________________________ Excitatory Synapse - ___________________________________________________________________ Neurotransmitters are quickly removed from the synaptic cleft through _______________, __________, and ________________. Functions of Acetylcholine 1. 2. 3. 4. Temporal summation is summation from (one/multiple) neuron(s) and spatial summation is from (one/multiple) neuron(s). The ________ _____________ has a high density of Na​ channels and is where the action potential begins. Presynaptic Inhibition-___________________________________________________________ Presynaptic Facilitation-__________________________________________________________ ________________- many axons coming to one neuron _________________- axon terminals going out to multiple neurons Most _____________ alter synaptic transmission. Nervous Systems Material Energy Hypothesis: 1. Carnivores are __________ brained and have a __________ quality diet with a _________ intestinal tract. 2. Herbivores are __________ brained and have a __________ quality diet with a ___________ intestinal tract. ORGANIZATION The ________________________ is made up of the brain and spinal cord. The _________________________ is made of nerves extending to other parts of body. Afferent neurons send information from the (PNS/CNS) to the (PNS/CNS), whereas the efferent neurons send information from the (PNS/CNS) to the (PNS/CNS). ​ The ​ arasympathetic nervous system originates from the _____________ and _____________ regions, and is in charge of (fight or flight/rest and digest) and has a ______________________ preganglionic nerve fiber where _______________ is released and a _____________________ postganglionic nerve fiber where __________________ is released. ​ The ​sympathetic nervous system originates from the _____________ and _________________ regions, and is in charge of (fight or flight/rest and digest) and has a ______________________ preganglionic nerve fiber where _______________ is released and a _____________________ postganglionic nerve fiber where __________________ is released. Parasympathetic and sympathetic nervous systems work together to coordinate ________________ in mammals. Receptor Types Cholinergic receptors 1. Nicotinic: _________________________________________________________ 2. Adrenergic Receptors: ________________________________________________________ Glial Cells 1. _________________- the most abundant type that supports the neurons. 2. Oligodendrocytes - ___________________________________________________________ 3. 4. Muscle Cells Muscle Cells are specialized to produce ___________ and do ______________. Types (include if striated or unstriated and if it is voluntary/involuntary) 1. 2. 3. Myofibril-____________________________________________________________________________ ____________________________________________________________________________________ They make up (20/60/80/90)% of the muscle cell. The greater the density of the myofibrils in the cell, the ___________ the force. Thick Filaments are made up of _________________ and have _______________ and ______________ binding sites. Thin filaments are made up of __________________, ________________, and _________________. Action potentials begin at the _________ _______________ where there is an abundance of _______ channels. The signal travels down the axons where it is insulated by ________ ________________ and the action potential jumps from one ________ _____ ____________ to another until it reaches the ___________ _____________. Here, _____ ions enter the cell and stimulate the proteins to release ______________________ by ________________. The (voltage/chemically/mechanically) gated channels open and the action potential travels through the muscle cell to a ____-___________ which is attached to the (endoplasmic reticulum/sarcoplasmic reticulum/golgi body) which releases _____ ions through a ____________ gated channel. This enacts the _____________ ________________ mechanism where ____ ions bind with (troponin/actin/myosin/tropomyosin). When the myosin is attached to the thick filament, it must be aided by ________ and bind to the _______________________ binding site to allow it to slide. When the muscle is ready to be relaxed, ______ must return back to the (endoplasmic reticulum/sarcoplasmic reticulum/golgi body) through (active transport/diffusion/endocytosis) and 2+​ +​ +​ through (vesicles/Ca​ ATPase/Na​ -K​ pumps). Uses of ATP in muscle contraction 1. 2. 3. Repetitive Summation Twitch summation-_____________________________________________________________ tetanus - _____________________________________________________________________ Imagine you are in a high-intensity workout, and your muscles require ATP to contract, where is your body most likely to get it’s source of ATP from? (Phosphagens/Oxidative Phosphorylation/Glycolysis). Muscle Structure Tendons attach ______________ to ______________ and ligaments attach _____________ to _____________. Flexors _____________ a limb and extensors ________________ a limb. ​ __________________-signal molecules of the endocrine system 1. _____________________- chains of amino acids and hydrophilic (i.e. insulin) 1. Synthesized by (ribosomes/sarcoplasmic reticulum/preprohormones) 2. Released by (endocytosis/exocytosis). 2. Amines-_____________________________________________________________________ 1. ____________________- hydrophilic (i.e. Epinephrine and NE) 2. ____________________- lipophilic 3. _______________- derived from cholesterol (i.e. testosterone/estrogen) 1. Cholesterol is ______________ by diet and _______________ by enzymatic reactions, allowing them to ____________ across the plasma membrane and cholesterol is modified by the (adrenal glands/pituitary gland/thyroid/pineal gland). 2. Cholesterol is ________ stored by cells and is synthesized by ________-___________ _________________. 4. Prostaglandins-________________________________________________________________ There are __________+ types and have a (local/long distance) effect on other cells. How are hormones regulated? A. Negative Feedback B. Neuroendocrine Reflex C. Biological Rhythms D. All of the Above A ___________ endocrine gland may produce (multiple/one) hormone(s) and a single ____________ may be secreted by (one/multiple) gland(s) and can have (multiple/one) target cell(s). If epinephrine is in the blood and headed to signal another cell, how will it cause a change in the target cell? A. Ion Fluxes B. Second Messengers C. Transcription Factors D. All of the Above ______________- the hormone secreted from the stomach that makes an organism hungry ​ ​ 1. 2. 3. 4. 5. 6. The posterior pituitary gland _____________ hormones and does not _______________ hormones. The anterior pituitary gland ______________ hormones and _________________ hormones.
