Muscular System: Part I

Foundations (No Pun Intended!)

100

There are this many bones in the human body.

What are 206?

200

The skeleton has these primary functions. 

What are: 

1. Provide structural support and shape

2. Protect vital organs

3. Storage site for minerals (Calcium + Phosporous)

4. Produce RBCs

300

There are this many muscles in the body.

What are 650?

400

The muscles are involved in these processes.

What are: 

1. Locomotion & movement

2. Convert chemical energy into Kinetic

500

The definition of muscle.

What is a CONTRACTILE tissue, found in ANIMALS, that acts by CONTRACTING.

Functions: Muscular System

100

A ligament does this. 

What is bind bone to bone?

200

A tendon does this. 

What is bind muscle to bone?

300

What are the key functions of the muscular system. 

What are: 

1. Movement (Voluntary & Involuntary)

2. Stability and Posture

3. Joint Stability

4. Heat Production

5. Circulation and Digestion

400

The three muscle types.

What are: 

1. Skeletal (Striated)

2. Smooth (Visceral)

3. Cardiac

500

This type of muscle has many NUCLEI, is STRIATED, CONTRACTS VOLUNTARILY, and is ATTACHED to the skeleton.

What is Skeletal muscle?

Functions: Muscular System Continued

100

These are LONG & TAPERED at each end. They have ONE NUCLEUS, LINE THE INTERNAL ORGANS, contract INVOLUNTARILY.

What are SMOOTH Muscles?

200

This forms the walls of the HEART. Contains both SMOOTH and STRIATED features. INVOLUNTARY control. 

What is CARDIAC muscle?

300

These cells are STRIATED and TUBULAR. They have MANY NUCLEI. They contract VOLUNTARILY. They are mostly ATTACHED to BONES of SKELETON. 

What are SKELETAL muscle cells?

400

The are NON-STRIATED, have ONE NUCLEUS, contract INVOLUNTARILY, found in the WALLS of the INTERNAL ORGANS. 

What are SMOOTH muscle cells?

500

These are STRIATED, TUBULAR, and BRANCHED. They have ONE NUCLEUS. They contract INVOLUNTARILY. They are found in the walls of the Heart. 

What are CARDIAC muscle cells?

Muscle Function: Skeletal Muscle

100

It SUPPORTS THE BODY and MAKES BONES MOVE. It helps MAINTAIN A CONSTANT BODY TEMPERATURE. It helps PROTECT THE INTERNAL ORGANS and STABILIZE THE JOINTS.

What is SKELETAL muscle?

200

Skeletal muscles do this when they CONTRACT.

What is SHORTEN?

300

Skeletal muscles do this when they RELAX.

What is LENGTHEN?

400

Skeletal muscles are arranged in what is known as these types of pairs. It means they work against each other to produce movement involving a joint.

What is ANTAGONISTIC pairs?

500

Muscles can only do this, they cannot do this.

What is PULL? (vs. push)

Muscle Function: Skeletal Application

100

When the bicep muscle contracts this muscle relaxes. 

What is the TRICEPS muscle?

200

This muscle contracts when the Biceps muscle is relaxed.

What is the TRICEPS muscle? 

300

This muscle is known as the EXTENSOR of the elbow joint.

What is the TRICEPS muscle?

400

This muscle is known as the FLEXOR muscle to the Triceps.

What is the BICEPS muscle?

500

The quadriceps act as the primary knee _________ (straightening the leg), while the hamstrings act as the primary knee _______ (bending the leg).

What is EXTENSOR (Quad) and the FLEXOR (Hami)?
