• Cartilaginous joints (little mobility)
  • Syndesmosis (inferior tibiofibular)
  • Synchondrosis (rib or sternum)
• Synovial (high mobility)
  • Artrodia joint (carpal ligament wrist)
  • Condyloid (biaxial and spherical line radio and carpal bones)
  • Ball and socket joint (multiaxial, spherically shoulder, elbow)
  • Trochlea (hinge ankle, knee)
  • Saddle (thumb)
  • Pivot (trochus radioulnar joint)

Bone Structure

• Vein, nerve, artery, Haversian canal, osteoblasts, lamellae, blood vessels, osteons
• Bone marrow, spongy bone, artery, vein, cortical bone, osteon, periosteum, nerve

Types: Smooth, cardiac, skeletal (voluntary/striated)... Continue reading "Human Anatomy: Bones, Muscles, Joints, and Posture" »

In the world of body expression, we can differentiate three groups: without the use of words, using words, and with music.

Without the use of words:

These are forms of rich verbal communication. They use basic elements of body expression as a fundamental form of communication. They are used for physical education and movement since body language is a fundamental communication channel.

Mime:

Mime dates back to Ancient Greece, involving two or three characters, and the representation was entirely silent. In Rome, it became a popular genre, and in the first farces, expression relied on oral communication. Over time, oral expression was lost, and mime could be used for political satire or retaliation. Mime is considered the first form of expression... Continue reading "Body Expression in Performing Arts: Mime, Theater, and Dance" »

**Retrocapsular Orthoses**

Stability Goal: Angled floor redistributes force vectors, increases propulsion time, and provides an antalgic effect.

**Subphalangeal Orthoses**

Aligned with the target, it increases support, stops rolling. Headlamp goal for Dynamo goal cushion, metatarsal, and diminishes impact angle.

**Hardness**

• Crosslinking Time: Maximum 30-60 minutes, decreased 12-24 hours, lasts 3-4 weeks (defined). The same values apply to a maximum duration of 20 minutes.
• Catalyst Quantity: Double the amount of catalyst for softer silicones increases the maximum, but the definition varies. Do not crosslink before.
• Type of Paste: Paste is less than the maximum duration, crosslinked slower. Half paste (slow catalyzation) lasts less than the maximum

The Role of Memory in Intellectual Development

Memory is an important factor in intellectual development, influencing thought processes and information processing. Vygotsky considered the relationship between thought and memory, stating that for a young child, "to think means to remember." Current studies focus on the theoretical and evolutionary aspects of storage, coding, and retrieval. These are important from an educational point of view as they allow us to understand different memory strategies in children's short-term memory.

Short-term memory allows us to retain data briefly. For example, a child may remember the mobile toy immediately after seeing it. However, if strategies are not used to retain the information, it will be forgotten.... Continue reading "Memory, Cognition, and Psychomotor Development in Early Childhood" »

Math Operations

Operations with Parentheses

Perform multiplications and divisions first, then additions and subtractions. When simplifying fractions, the greatest common divisor should be used to reduce both the numerator and the denominator.

Expressing Fractions as Decimals

When the decimal is purely periodic (e.g., n = 235.2): The numerator is the number without the decimal point minus the non-periodic part, and the denominator is as many 9s as there are figures in the period.

When the decimal is mixed periodic (e.g., 1.372): The numerator is the number without the decimal point minus the non-periodic part. The denominator consists of as many 9s as there are periodic figures followed by as many 0s as there are non-periodic figures after the decimal... Continue reading "Math Operations" »

What is Strength?

Strength is the capacity to overcome resistance through muscular action.

Types of Strength

• Force-Resistance: Capacity used for multiple repetitions against prolonged resistance. Loads are light/medium.
• Explosive Force: Capacity to overcome a load with muscle contraction velocity. Done in the shortest time possible.
• Maximum Force: Capacity to oppose a maximum load through voluntary muscle contraction. May involve motion or not.

The Locomotor System

The locomotor system is formed by bones, muscles, and joints. Muscles cover bones. They are formed by fascicles, muscle fibers, myofibrils, and myofilaments (actin and myosin). The function of an agonist muscle is to stretch when its antagonist contracts.

Muscle Contractions

Types of Contractions

• Concentric

General Adaptation Syndrome (GAS) and Supercompensation

The body's response to stress, such as physical exercise, follows a predictable pattern known as the General Adaptation Syndrome (GAS). This process involves a series of reactions designed to overcome fatigue and adapt to a higher level of equilibrium.

Phases of General Adaptation Syndrome

• Alarm Phase: The initial reaction to a new or increased stressor, causing an imbalance in the body.
• Resistance Phase: The body attempts to adapt and cope with the stressor, leading to improved function.
• Exhaustion Phase: If the stress is too prolonged or intense, the body's resources become depleted, leading to fatigue and potential decline in performance.

The Supercompensation Phenomenon

Following the resistance... Continue reading "Optimizing Physical Performance: Principles and Training Methods" »

Keystone

(L) Between the neck and the manubrium. (F) Shrugging; works with other muscles to bring the head forward, backward, and to either side.
