Question
22) Name two important regulatory muscle proteins which are involved in muscle contraction b. 23) Myoglobin: a. binds oxygen for acrobic respiration with the musele cell b. binds actin to myosin c. blocks myosin binding sites d. separates one sarcomere from another 24) The attachment of a muscle to the bone that remain stationary is known as the a. insertion b. origin c. proximal attachment d. distal attachment 25) The cell membrane of a muscle fiber is called a. plasmalemma b. sarcolemma c. myolemma d. sarcomere 26) Which of the following are the parts or components of neurons a. brain, spinal cord, and vertebral column b. dendrite, axon, and cell body c. sensory and motor d. cortex, medulla and sheath 27) During action potential the charge inside the axon changes from positive to negative. a. true b. false 28) A nerve impulse is the way a sensory neuron receives information. a. true b. false 4Explanation / Answer
22. troponin and tropomyosin
23 Myoglobin: binds oxygen for aerobic respiration with muscle cell (a)
24 attachment of the muscle to the bone that remains stationary is known as its: origin
25 (b) Sarcolemma
26 (b) dendrites, axon, and cell body.
27 false: the axon at resting state is negatively charged(-70mv) action potential changes the charge and bring it to 0mv for a brief period of time
28: False: Nerve impulses are the way by which neurons transmit information.Sensory neurons receive information through stimuli like taste smell, vision or touch
29. sarcomeres (d)
30 (a) The sarcoplasmic reticulum is a specialized type of smooth endoplasmic reticulum
31 (b) perimysium
32 (a)both brain and spinal chord
33 white matter: conduct nerve impulses to and from the brain
grey matter: receives and integrates incoming and outgoing info to perform spinal reflexes.
Reflex: fast and automatic response to changes int eh environment
integrating center- one or more regions within CNS that relay impulses from sensory to motor neurons
34. true: CSF is produced mainly by a structure called the choroid plexus in the lateral, third and fourth ventricles of the brain
35 oxygen and glucose are vital for brain functioning.
36.choriod plexus(a)
37 sensory neurons: nerve cells in the nervous system which are responsible for converting external stimuli from the organism's environment into internal electrical impulses to generate a response.
38 sensory receptors: Also known as dendrites of sensory neurons specialized for receiving specific kinds of physical stimulus from the environment, whether internal or external
39 motor neurons Those that carry impulses away from the brain and other nerve centers to muscles they are the efferent neurons that originate in the spinal cord and synapse with muscle fibers to facilitate muscle contraction upon receiving an impulse
40 effector: an organ or a cell that responds to a stimulus from nerve .eg: muscle producing saliva from the salivary gland. upon food sight or smell.
