Review Chapter 10-12
Ch 10
The unit of muscle structure that is composed of bundles of myofibrils, enclosed within a sarcolemma, and surrounded by a connective tissue covering called endomysium is a muscle fiber.
The plasma membrane of a skeletal muscle fiber is called the
Sarcolemma
In a skeletal muscle fiber, Ca2+ is stored within the sarcoplasmic reticulum
The bundle of dense regular connective tissue that attaches a skeletal muscle to bone is called a(n) tendon.
In excitation-contraction coupling, the transverse tubules function to conduct an action potential into the sarcoplasmic reticulum.
During muscle contraction, the I band shortens or narrows
What event causes troponin to regain its original shape in muscle relaxation? return of Ca2+ into the sarcoplasmic reticulum
A storage form of energy unique to muscle tissue is
creatine phosphate
Which of the following changes in skeletal muscles is associated with aging?
The number of satellite cells in muscle decreases
Ch 11
Which statement is true about an agonist?
It is the primary muscle that produces a movement.
When the left and right contract, they flex the head and neck
Sternocleidomastoid
When this large muscle contracts, the vertical dimensions of the thoracic cavity increase.
Diaphragm
This muscle depresses and adducts the eye superior oblique
Each of these muscles can laterally flex the vertebral column except the transversus abdominis.
All of the following muscles flex the forearm except the anconeus. Which muscles originate on the ischial tuberosity and extend the thigh plus flex the leg?
Quadriceps
Ch 12
The cell body of a neuron does all of the following except release neurotransmitter into the synaptic cleft.
Neurons that have only two processes attached to the cell body are called
Bipolar
Which neurons are located only within the CNS? interneurons EPSPs are caused by the movement of
Na+ into the cell.
The glial
