Lecture 1 Flashcards
Name the 4 major types of tissues that compose the body and there definition with an example of each
Epithelial tissue = Covers body surfaces, hollow organs, body cavities, ducts and forms glands -> Epidermis
Connective tissue = Protects and supports the body + organs -> Fascia
Muscle tissue = Provides movement and generation of force -> Biceps
Nervous tissue = initiates and transmits nerve impulses (signals) that help control and coordinate body activities -> Brain
Name some of the major functions of bone tissue and the skeletal system (5 total)
- support and protection
- movement
- mineral storage and release
- site of hemopoiesis, occurs in red marrow
- strage of energy (lipid storage) in yellow marrow
Name the 3 types of muscle tissue with caracteristiques
Skeletal muscle : striated, voluntary, moves bones and in some cases skin and other soft tissues
Cardiac muscle : striated, involuntary
Smooth muscle : non-striated, involuntary
Name some of the major functions of muscle tissue (4 total)
- Movement of body parts or substances within the body
- Maintenance of posture
- Joint stabilization
- Heat generation
Explain the anatomical position (5 lines)
- Person stands upright
- Upper limbs at sides, palms face anteriorly
- Thumbspointed away from the body
- Feet flat on the floor, toes point forward
- Head and eyes directed straight ahead
Name the 3 reference planes
- Sagital
- Frontal
- Transverse
Name the 5 types of reference directions
- Anterior _ Posterior
- Superior _ Inferior
- Medial _ Lateral
- Proximal _ Distal
- Superficial _ Deep
Name the 3 types of joints by function
- Synarthroses = Immovable joints
- Amphiarthroses = Slightly movable
- Diarthroses = Freely movable
Name the types of joints by structure
- Fibrous joint (suture, syndesmosis)
- Cartilaginous (synchondrosis, symphysis)
- Synovial
Name the 2 fibrous joints
- Suture = bones are tightly bound by very small amount of fibrous tissue, only between bones of the skull
- Syndesmosis = bones are connected by longer bands of fibrous tissues, ex : between radius and ulna. Less movement because te connecting fibres are short
name the 2 cartilaginous joints
- Synchondrosis : Hyaline cartilage connects the bones (immobile), ex : 1st ribs cartilage and manubrium
- Symphysis : Fibrocartilage connects 2 bones, ex : symphysis pubis
Name the 5 componets of all synovial joints and explain briefly what a synovial joint is
Synovial joints are the most movable joints in the human body (diarthroses)
- Articular cartilage = on the ends of articulating bones
- Joint cavity = holds synovial fluid
- Articular capsule = encloses join cavity
- Synovial fluid = viscous fluid
- Ligaments = reinforces the join
Explain some of the movements at synovial joints
- Flexion
- Extension
- Abduction
- Adduction
- Circumduction = 1,2,3,4 together (circle)
- Rotation
- Gliding
- Etc…
T or F, Muscles are attached to bones by tendons
True
The 3 general rules of muscles and their function?
- Muscle has to cross the joint in order to produce movement at that joint
- Muscles shorten when they contract
- Muscles cannot push, only pull
