Epimysium

layer of dense connective tissue that surrounds the entire muscle, also known as deep fascia

Perimysium

- extensions of epimysium that divide the muscle into bundles of muscle cells called fascicles

Endomysium

extension of perimysium that penetrates each pascicle and surrounds each individual muscle cell

Nuclei

skeletal muscles cells are multi nucleate; the nuclei typically lie close to the sarcolemma and appear like bumps

Sarcoplasm

cytoplasm of a muscle cell

Sarcolemma

plasma membrane surrounding the muscle cell

Nuclei

skeletal muscles cells are multi nucleate; the nuclei typically lie close to the sarcolemma and appear like bumps

Striations

dark and light stripes in each muscle cell

What are you trying to discover in the rabbit muscle experiment?

If the rabbit muscle cells would contract if chemical were added, and what combination of chemicals would produce the greatest contraction (ATP solution, mineral salt solution, ATP and mineral salt solution)

input device

recording electrodes or input transducers may serve as an input device which picks up the biological event. A recording electrode is used if the event is electrical, such as nerve impulse.

A recording electrode

is used if the event is electrical, such as nerve impulse.

The input transducer

is used of the event is non-electrical, such as a muscle contraction, movement, pressure or airflow. Input transducers detect the physiological event and convert it into an electrical signal

interface unit

device that receives signs from the electrodes or transducers, amplifies the magnitude of the signal, and forwards the information to to the computer. (MP35 refers to the particular model of the interface that is part of the BIOPAC INC. DAS

computer display:

the magnified signal from the interface unit are logged to a data file and converted to a graphic record for display

Channel

composed of the input unit (recording electrodes or transducer), the interface unit (MP35) and computer monitors display. The MP35 can receive up to four signals simultaneous making it multi-channel

multi-channel

(able to record multiple events at once). Ex: a subjects pulse, respiratory rate and blood pressure could be recorded on channels 1,2,and 3, respectively and simultaneously

What biological event will you record with the data acquisition in this weeks lab? .

Physiological event= pulse

BPM

beats per minute

DeltaT

time from beginning to end of a selected area
