Key factors in establishing membrane potential (Vm):
-relative permeability of NA+ and K+
function of leak channels (PK+ > PNA+)
-NA+-K+ pump establish conc. gradient

According the load-velocity relationship of muscle contraction
a. lengthening contractions are associated with the highest force levels.
b. shortening contractions are associated with the highest force levels.
c. all types of contractions gener

ANATOMY EXPLORATION #1
The Human Skeleton
The Human Skeleton consists of two portions: The axillary portion (consisting of the trunk and head) made up of 80
bones, and the appendicular portion (consisting of the framework for the limbs and including the p
ANATOMY EXPLORATION #3
1. General Overview
The upper arm consists of a single bone, the humerus. The upper arm is also referred to as the brachium.
Together, the articulation of the Clavicle, Scapula, and Humerus forms the shoulder joint. This lab will

The amount of force is related to the amount of cross bridges made in the muscle.
Length of the muscle determines how much force you can produce.
Amount of overlap between thick and thin filaments.

Electrolytes and water
More adipose tissue > smaller proportion of water in body
(women have smaller water proportion)
Intracellular fluid compartment > all fluid in trillions of body cells,
all cells have similar composition, 40% of body weight.
REGULATION OF INTRACELLULAR FLUID COMPOSITION
Plasma membranes separate intracellular/extracellular fluid
compartments > selectively permeable (impermeable to
proteins/large molecules), proteins remain in intracellular fluid.
Electrolytes are actively tra
