The long, shaft-like middle portion of a bone such as the femur

Bones are surrounded by a very thin, very tough outer covering called this

Long bones have an epiphysis made of this type of bone; it is very porous and lightweight

Bones that develop between two sheet-like layers of connective tissue are called this

These microscopic chambers found in bone tissue are responsible for housing osteocytes and are often found in concentric circles surrounding a central canal containing blood vessels for nourishment

A muscle cramp can be caused by a lack of this all-important energy storing cellular molecule

A condition that sets in shortly following death. It is caused by constant contact between myosin and actin due to lack of ATP

The idea that when a muscle fiber contracts it will do so with all of its strength

A unit that extends the length of a muscle fiber and is composed primarily of actin and myosin is called this

The potion of this myogram labeled A is called

A

The part of a typical neuron that receives incoming signals from other neurons or from sensory organs

Myelinated nervous tissue looks like this

The charge difference found across a neurons while at resting membrane potential

Positive outside,Negative inside

The cause for repolarization of a neuron following an action potential

The four types of neruoglial cells and their primarly function

Astrocytes - Blood brain barrier

Oligodendrocytes - Myelination of CNS neurons

Ependymal cells - Produce and circulate CSF

Microglial cells - Phagocitize bacterial cells in CNS

Responsible for storing fat in your bone tissue

The primary function of red bone marrow is to form these

Within the nervous tissue known as the meninges, cerebrospinal fluid can be found in this space

In muscles, the layer of connective tissue that separates the muscle into fascicles

In the spinal cord, the anterior horns contain these kinds of axons

This neurotrasmitter is responsible for stimulating muscle fibers to contract

Following a fracture, these cells will help build new bone tissue

Movement of this ion across the neuron cell membrane results in depolarization during a action potential

Muscle fibers that are likely to respond to intense, heavy loads

The correct order of its events are:

1.Receptor2.Sensory neuron3.Interneuron4.Motor neuron5.Effector

The name of the part of an action potential at which the neuron’s potential in greatly reduced below that of resting membrane potential is called this

Slow twitch fibers respond to this type of exercise

Which channels are open at the point labeled A on this graph of An action potential?

A

The part of an action potential that acts as the tipping point that sends the neuron through the sequence of depolarization and repolarization

The repeating units of a myofibril
