Summary
The jaw acts as a syllable frame, not crucial for timing speech segments. Lip and tongue movements, however, define these acoustic segment boundaries.
Area of Science:
- Speech Science
- Linguistics
- Phonetics
Background:
- The jaw is traditionally viewed as a syllable articulator, opening and closing rhythmically with syllables.
- Jaw opening extent correlates with syllable strength for a given vowel.
Purpose of the Study:
- To investigate the relationship between syllabic and segmental articulations and acoustic segments.
- To determine the jaw's role in speech timing relative to other articulators.
Main Methods:
- Analysis of electromagnetic articulography data from 18 Southern Swedish speakers.
- Testing hypotheses from the Descriptive Approach to Segmental Articulations.
- Dividing articulatory movements into fast intervals and steady states.
Main Results:
- Confirmed previous findings for lip and tongue tip articulations.
- Jaw movements do not align with acoustic segment boundaries; its steady states are shorter than speech segments.
- Coda place of articulation affects the jaw cycle; syllable type affects jaw closing, but not jaw cycle edges.
Conclusions:
- The jaw is a syllable articulator providing a framework, not crucial for acoustic segment timing.
- Lips and tongue tip function as segmental articulators, defining speech content.
- Syllable borders are not significantly affected by the place of segmental articulation.

01:11The Auditory Ossicles
1.7K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

01:20Structural Classification of Joints
3.4K
Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
A fibrous joint is where the adjacent bones are united by fibrous connective...

01:28Articulations of the Vertebral Column
1.9K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

01:26Bone Markings
5.3K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

01:16Structural Joints: Synovial Joints
3.5K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
