MUSCLE TISSUE. A primary tissue type, divided into: skeletal muscle cardiac muscle smooth muscle.
Muscular System Functions Body movement Maintenance of posture Production of body heat Communication Constriction of organs and vessels Heart beat.
The Cytoskeleton. Intermediate Filaments 8-10 nm in diameter Four types: basis of aa sequence actin & tubulin -> globular protein, cell type.
LECTURE 13: MUSCLE CONTRACTION & MOTOR UNITS REQUIRED READING: Kandel text, Chapter 34 Skeletal muscle is made up of long, multinucleated muscle fibers.
Motor Proteins. 2 Motor Systems Actin-based motility: motor proteins are myosins Tubulin-based motility: motor proteins are kinesins and dyneins.
Muscular Control of Movement. Review of Anatomy Types of Muscles –Smooth: blood vessels and organs –Cardiac: heart –Skeletal: muscles for movement.
Skeletal Muscle Physiology How do contractions occur? Remember that muscles are excitable.
