Balanz Exam Anatomy Flashcards
Why do we learn anatomy and physiology
1-To understand the body structure
2-How the body works
3-Practice yoga in a safe way to avoid injuries
What is Anatomy
Study about the body structure and relationship between the different parts
What is physiology
Study on body function and how the body works
What are the organ systems
Organ systems
1-Circulatory (cardiovascular, lymphatic)
2-Respiratory (O2 and CO2)
3-Digestive (digestive tract and glands)
4-Urinary / Excretory (kidneys and urinary tracts)
4-Reproductive - uterus / testes
5-Muscular - (skeletal-, cardiac-, smooth muscles)
6-Skeletal (bones, cartilage, tendons, ligaments, fascia)
7-Endocrine (hormonal)
8-Lymphatic
9-Immunity
10-Integumentary (skin hair nails)
11-Nervous (central nervous system (CNS): brain and spinal cord, peripheral nervous system (PNS): nerves
What are anatomical position
Mountain pose
Comparing relative position of 2 body parts
1-Anterior - towards front of the body
2-Posterior-towards back of the body
3-Distal - refers to limbs towards the tips
4-Proximal-refers to limbs towards the root
5-Ventral - on the front of the body
6-Dorsal -on the back of the body
7-Lateral - away from the midline
8-Medial - towards the midline
9 Superficial - towards the body surface
10-Deep-inside the body
11-Superior - higher than or above the head (cranial)
12-Inferior - lower than or below the head (caudal)
13-Transverse - Horizontal, across the body
14-Longitudinal - vertically along the body
What are the different movements
Different movements
1-Flexion - decreasing / closing an angle / bending
2-Extension - increasing / opening an angle / extending
3-Abduction - moving away from the center line
4-Adduction - moving towards the center line
5-Circumduction - circular movement combines abduction, adduction, flexion, extension
6-Medial (internal rotation)
7-Lateral (external rotation
8-Pronation - rotation of forearm so palms face down
9-Eversion - rotation of ankle so sole points away from the other
10-Supination-rotation of forearm so palm faces up
11-Inversion - rotation of the ankle so the foot points towards the other
Anatomical Planes
It is similar to the position of the famous Vitruvian Man (or mountain pose)
1-A person standing upright, facing forward.
2-Arms straight and hands held by the hips, palms facing forward.
3-Feet parallel and toes pointing forward.
1- Saggital - flexion, extension, anterior, posterior movements
2-Transverse - rotation, pronation, supination
3-Frontal - abduction, adduction
What is bone and why is it important
Bone is the main supporting tissue of the body 1-Support 2-Protection 3-Movement 4-Storage of nutrients / minerals 5-Production of blood
How does form and shape of bones reflect function
Form and shape reflect the function of the bone.
1-Long - leverage, support
2-Short - weight bearing
3-Flat - protection / place for broad muscles to attach
What is Cartilage
1-Cartilage is a resilient, smooth elastic tissue covering and protecting the ends of the long bones at joints
2-Found in ear, ribs, nose
3- Not as hard and rigid as bone. Stiffer and less flexible than muscle
What are the 3 types of cartilage
1-Hyaline cartilage (Low-friction, wear-resistant tissue present within joints or at the end of long bones, designed to bear and distribute weight)
2-Elastic cartilage -very flexible, present in ear, larynx and epiglottis
3-Fibro cartilage -tough and inflexible, found in the knee and between vertebrae
What is hyaline cartilage
Hyaline cartilage has a low coefficient of friction
1-Resists wear and tear
2-Somewhat elastic
3-Compressed slightly
What is a Tendon
Tendon connects muscle to a bone
Origin - usually the most proximal place where tendon connects the muscle to the bone
Insertion - usually the most distal place where the tendon connects the muscle to the bone
What is a Ligament
Ligaments connects bone to bone
Limit the range of movement
What is Fascia
Fascia is a thin matrix of tissue - found all over the body - contributor to our health, well being and flexibility
What is a Joint
A joint is a specialised region where bones are connected by soft tissues, allowing range of motion to be safe as possible. Their shape reflect their function
What is a highly moveable joint called
Synovial Joint
1-Wherever bones come into contact with one another They are covered by hyaline cartilage
2-The areas between the bone ends are bathes in synovial fluid. There is no blood supply
3-Synovial membrane surrounds the space, the outside of a fluid filled balloon
4-Thick strong membrane surrounds this, called the joint capsule
Examples of synovial joints
1-Ball and socket (shoulder/hip) 2-Hinge (knee/elbow/finger) 3-Ellipsoid (radiocarpel) 4-Saddle (thumb) 5-Pivot(cervical vertebra 1-2) 6-Gliding (sacroiliac)
Agonists
A muscle that causes a movement
A muscle contracts to produce a certain action in a joint (muscle produces a movement against a load)
Agonists
1-A muscle that causes a movement
2-A muscle contracts to produce a certain action in a joint (muscle produces a movement against a load)
3- prime movers
Antagonist
1-A muscle that inhibits a movement
2-A muscle that relaxes while the agonist contracts - a muscle that opposes a movement against a load
3- Muscles that produce an opposing joint torque to the agonist muscles
What are the types of muscular contraction
Isotonic contraction
Concentric
Eccentric
Isometric contraction
No motion / movement (downward facing gog in holding phase)
what type of contraction is the downward facing dog in holding phase
Isometric contraction (no motion in the joint) - static
what type of contraction is the chaturanga
Isotonic contraction
1-motion at the joint
2-tension is constant
3-load does not change
Quadriceps - stretching from chair to standing
Against gravity
Concentric
Quadriceps lowering down into chair
With gravity
Eccentric
What is fascia
Fascia (latin) means band or bundle
1-Fascia is a soft tissue component of the connective tissue system
2-Surrounds and penetrates muscles, bones, organ, nerves and other structures in the body
3-Interconnected 3D web of tissue
4-Responsible for structural integrity, support, protection, shock absorption and sensory neurons
5-Essential for intercellular communication
6-Helps to guide the alignment of our blood vessels and nerves
7-It is the home for fat cells.
What are the 3 types of fascia
1-Superficial Fascia (lies just beneath the skin)
2-Deep Fascia (single 3D structure) envelops every muscle, organ connecting them all together and holding everything in place
3-Loose Fascia - intervening layer between deep and superficial fascia. Permits motion of slide and glide all over the body.
