7-8 Unа quinceаñerа Using the infоrmatiоn yоu learned in the Perfiles section of this chapter, decide whether each statement is Cierto or Falso. Hola, soy Chela y vivo en La Habana, Cuba. Muchas veces la gente de afuera1 nos pregunta por qué no tenemos Internet en nuestras casas. Pues, la razón es porque, por ahora, el gobierno no nos lo permite. Solo tiene Internet un 5% de la población y para ello se necesita un permiso especial del gobierno. Sin embargo, aquí recientemente el gobierno está permitiendo áreas de wifi en algunos parques de la capital, así que por fin podemos conectarnos con amigos y familiares por correo electrónico, mensajes de texto y redes sociales. ¡Pero no creas que es fácil! Para empezar, los parques son muy populares y en las horas en las que van más personas, es casi imposible conectarse. Además, el ancho de nuestra banda2 es peor que en otras partes del mundo, es decir, ¡es muy, muy lenta3! Otro problema es que para la mayoría de la población, cuesta un dineral, ¡dos dólares por hora y el salario promedio de un cubano es de 25 dólares al mes! Para poder tener acceso a Internet, tienes que comprar una tarjeta4 de ETECSA (Telecomunicaciones de Cuba), la empresa oficial del gobierno; después, tienes que encontrar una zona de wifi, y finalmente, tienes que conectarte. Pero hay beneficios en esta metodología. Muchas veces en los parques de wifi te encuentras con amistades que no ves desde hace tiempo, y aunque no puedas conectarte a Internet, te conectas otra vez con ellas en persona. Esto también es muy lindo. 1foreigners 2bandwidth 3slow 4card 1. En Cuba, hay Internet en muchas casas. [cf1] Cierto Falso 2. Algunos parques ofrecen wifi. [cf2] Cierto Falso 3. Cuando hay muchas personas es muy difícil conectarse. [cf3] Cierto Falso 4. En Cuba, tener Internet en casa no cuesta nada. [cf4] Cierto Falso 5.

Mаtch the missing step tо the cоrrect step thаt shоuld be present. Eаch missing step is numbered and labeled in BOLD UNDERLINE. Hand touches something hot Stimulus is applied to the dendrite of a sensory neuron causing a graded potential that moves to the soma Graded potential spreads from soma towards the axon hillock along soma membrane MISSING STEP 1 Graded potential depolarizes the axon hillock and activates/opens voltage gated Na channels Na enters the cell and depolarizes the membrane further More Na channels open allowing more Na into cell MISSING STEP 2 All Na channels activate/open MISSING STEP 3 Na channels begin to close Potential decreases towards RMP Voltage gated K channels open and K exits the cell (repolarization) MISSING STEP 4 Na channels inactivate and close MISSING STEP 5 AP propagates along the axon to the next area of unmyelinated membrane (which is at RMP and is called a node of Ranvier) Myelin sheaths prevent depolarizing current from dissipating At the node, voltage gated Na channels activate/open causing depolarization Another AP is triggered and propagates to the next node; this continues until the AP reaches the axon terminal MISSING STEP 6 Ca causes synaptic vesicles with neurotransmitters (NT) to form Vessicles fuse with the terminal membrane and release NT into synaptic cleft via exocytosis MISSING STEP 7 Binding causes ion channels to open and establish a graded potential in the next neuron MISSING STEP 8 This process repeats until the first order neuron (ganglia) is reached at the spinal cord The first order neuron sends the signal through an ascending pathway to the brain stem (where pain sensory is processed) Brain stem sends the incoming signal for interpretation to the somatosensory cortex Somatosensory cortex processes and interprets the signal and sends out a new signal to move the hand from the heat source Signal is sent along a descending pathway to a first order neuron (ganglia) at the spinal cord The first order neuron sends the signal to the neuron after it and down a line of neurons until the final neuron is reached (final neuron is a motor neuron attached to a muscle fiber) AP (signal) arrives at the axon terminal of the motor neuron (attached to the muscle fiber) MISSING STEP 9 Ca causes synaptic vesicles with acetylcholine (ACh) to form Vessicles fuse with the terminal membrane and release ACh into the neuromuscular junction (NMJ) via exocytosis MISSING STEP 10 Ion channels of the sarcolemma open Na enters and K exits the cell More Na comes in than K going out producing an end plate potential ACh is re-uptaken, degraded or is diffused away from the NMJ MISSING STEP 11 T tubule proteins change and stimulate the sarcoplasmic reticulum (SR) MISSING STEP 12 Ca binds to troponin which causes tropomyosin to move and expose the binding sites on actin MISSING STEP 13 ADP and P release from the myosin head MISSING STEP 14 Sarcomere shortens thus contracting the muscle fiber (this occurs in many sarcomeres) Muscle contracts and movement of the hand from the heat source begins to occur MISSING STEP 15 Ca is removed from troponin and is taken back up into the SR Tropomyosin moves and covers the actin binding sites ATP on the myosin head hydrolyzes to ADP and P MISSING STEP 16
