What distinguishes ligaments from tendons within the muscular and skeletal systems?
What distinguishes ligaments from tendons within the muscular and skeletal systems?
- Ligaments form the skeletal system while tendons are part of the muscular system
- Ligaments stabilize joints while tendons facilitate movement of bones (correct)
- Ligaments are more elastic than tendons

Study Notes
Course Information
- Course: KINE 2850 Structural Kinesiology
- Lecture: 1 - Introduction
- Institution: East Carolina University
- Location: Greenville, NC
Structural Kinesiology Definition
- Structural kinesiology combines the anatomical elements of the human body with kinesiology, the study of human movement.
- It analyzes movement by identifying anatomical elements within the body.
Skeletal System
- Structure: The skeletal system includes rigid bones (though not entirely rigid) and flexible joints, which are also not entirely flexible.
- Axial skeleton: Includes the trunk, spine, neck, and head.
- Appendicular skeleton: Consists of upper and lower extremities.
- Functions:
- Framework: Providing a basic framework for the body.
- Movement: Acting as attachment points for muscles, and functioning as levers for movement.
- Protection: Offering protection to internal organs.
- Mineral storage: Storing minerals.
- Blood formation: Producing blood cells.
Types of Joints
- There are 6 major types of joints:
- Hinge
- Ball and socket
- Pivot
- Saddle
- Gliding
- Condyloid
Muscular System
- Function: Exerting force through contraction.
- Types of contractions:
- Isometric: Muscle contracts but does not shorten (holds a position).
- Concentric: Muscle shortens (starts a movement).
- Eccentric: Muscle lengthens (stops or decelerates a movement).
- Muscle Nomenclature: Examples include Flexor digiti minimi. Includes:
- Origin: Proximal attachment point.
- Insertion: Distal attachment point.
- Line of pull (action/outcome): The muscle's action or result
- Impacts force production
Other Connective Tissues
- Tendon: Attaches muscle to bone to allow for movement.
- Ligament: Attaches bone to bone to provide stability to joints.
Anatomical Position
- Anatomical Position: A standard reference point for the body, with palms facing forward.
- All anatomical descriptions refer to this position.
Anatomical References
- Directional terms:
- Anterior: front of the body
- Posterior: back of the body
- Medial: toward the middle
- Lateral: toward the side
- Superior: above
- Inferior: below
- Proximal: nearest to the trunk
- Distal: farthest from the trunk
- Other terms:
- Superficial: near the surface
- Deep: beneath the surface
- Prone: lying face down
- Supine: lying face up
- Contralateral: relating to the opposite side
- Ipsilateral: relating to the same side
- Biarticular: crossing two joints directly
- Uniarticular: crossing one joint directing
Planes of Motion
- Sagittal: Divides the body into left and right halves.
- Transverse (Axial): Divides the body into top and bottom halves.
- Frontal (Coronal): Divides the body into front and back halves.
Axes of Rotation
- Anteroposterior: Rotational axis for movements occurring in the frontal plane.
- Mediolateral (Transverse): Rotational axis for movements occurring in the sagittal plane.
- Longitudinal: Rotational axis for movements occurring in the transverse plane.
General Movements
- Primary Movements—examples include:
- Flexion
- Extension
- Abduction
- Adduction
