The sliding filament model of contraction is used to help explain the phenomenon of muscle contraction in which thin filaments slide past thick filaments, thereby shortening sarcomeres. As you have already studied this semester, this can only happen through cross bridge attachment. List the two main proteins that are directly involved in forming cross-bridges.  

Take a photo of your work for #11-18 and submit to the Exam 2 Upload Assignment after you log out of Honor Lock.

Five long parallel wires in an xz-plane are separated by a distance d = 8.00 cm, have lengths of 10 m, and carry identical currents of 3.00 A out of the page. Each wire experiences a magnetic force due to the other wires. NOTE: Answers must include units, diagrams /drawings and all work/calculations must also be submitted via email to danrodri@fiu.edu by 7:20PM.    Draw the directions of the magnetic field and the corresponding forces in each of the wires on the diagram below. The magnitude of the net force on wire #1 due to the other wires is [F1]. The magnitude of the net force on wire #2 due to the other wires is [F2]. The magnitude of the net force on wire #3 due to the other wires is [F3]. The magnitude of the net force on wire #4 due to the other wires is [F4]. The magnitude of the net force on wire #5 due to the other wires is [F5]. The direction of the net force on wire #1 is [D1]. (ie. up, down, right, left, neither) The direction of the net force on wire #2 is [D2]. (ie. up, down, right, left, neither) The direction of the net force on wire #3 is [D3]. (ie. up, down, right, left, neither) The direction of the net force on wire #4 is [D4]. (ie. up, down, right, left, neither) The direction of the net force on wire #5 is [D5]. (ie. up, down, right, left, neither)

Name the 2 neurotransmitters used by the autonomic nervous system.  

Figure 14.1Using Figure 14.1, match the following:Cell body of a somatic motor neuron. 1.

A very long horizontal wire carrying a current I1 = 35.0 A to the left as shown is placed tangentially below a loop of radius r = 0.0200 m (the wires are insulated, so there is no danger of electrical contact). Find what current I2 must flow in the loop, and in what direction (CW or CCW), so that the net magnetic field at the center of the loop becomes zero. NOTE: Answers must include units.   The current I2 in the loop is [C1]. The direction of current I2 in the loop is [D1].

Two toroidal solenoids are wound around the same form so that the magnetic field of one passes through the turns of the other. Solenoid 1 has 700 turns, and solenoid 2 has 400 turns. When the current in solenoid 1 is 6.52 A, the average flux through each turn of solenoid 2 is 0.0320 Wb. NOTE: Answers must include units. The mutual inductance of the pair of solenoids is [M]. When the current in solenoid 2 is 2.54 A, the average flux through each turn of solenoid 1 is [flux].

After an intense final exam in Mr. Morales’ A&P course, you decide to hit the road for some fun in the sun at your favorite summer destination, South Padre Island. Keeping your social distancing, you make it to your favorite beach house, cooling off with your favorite beverage of choice by the ocean. Which branch of the ANS would predominate in this situation?

What is the main reason as to why the somatic nervous system relays information from the CNS to its effectors much quicker than the ANS?

The ANS innervates 3 different types of effectors organs as compared to the somatic nervous system. Name the 3 types of effectors of the ANS.
