Problem 19.1.21

Compare punctuated equilibrium and gradualism.

Step-by-Step Solution:

Step 1 of 3

BIO 2500 Exam 3 Motor Unit • 1 motor neuron and all the muscle fibers it innervates 1. An axon can branch and have many axon terminals, so a single axon can innervate multiple muscle 2. When a motor neuron transmits AP to muscle fiber it will cause all the muscle fibers it innervates to contract 3. Muscle fibers per motor unit may be just a few or more than a hundred Types of Muscle Contractions 1. Isotonic – muscle length changes a. Concentric – muscle shortens when it contracts i. ex. Biceps curls use both, concentric and eccentric; all jumping and throwing activities use both concentric and eccentric b. Eccentric – muscle lengthens when it cont
