Abstract:
The post-natal growth of the masticatory muscles in the rabbit was examined. By means of anatomical dissection and measurement, total muscle length, muscle fiber length, and muscle weight were determined in animals varying in age between one week and 36 months and exhibiting a 50-fold weight increase. Growth data were fitted by linear regression models with facial skull length used as the independent variable. Many deviations occur from size-dependent isometric growth. The muscles can be divided into three groups, according to their pattern of weight increase: The jaw openers grow negatively a

Abstract:
<em>The intensity of sheep&rsquo; muscle growth is divided into three groups: slow-growing, moderately growing and rapidly growing; weight and size of muscle fibers depends on functional activity. At the same time, the literature does not sufficiently cover the issues of weight growth of muscles and separate muscles. To achieve this goal, the carcasses obtained for dissection were carefully removed from the irrigation fat, then the muscles on the left side of each carcass were dissected. Each muscle was released from fat and then weighed with its tendons. In the process of dissection the muscl

A description of cellular energetics of muscular contraction is given in terms of the rates and extents of high-energy phosphate splitting during contractile activity, in terms of high-energy phosphate resynthesis by respiration and net anaerobic glycolysis, and in terms of the associated uptake and/or release of H+. These chemical changes have been studied quantitatively by rapid freeze-clamping methods and by 31P-NMR methods. The pattern of chemical changes in a fast-twitch glycolytic muscle is rapid depletion of phosphocreatine and later ATP levels, cellular acidification, and a much slower

Abstract:
The human tongue is a muscular hydrostat, comprising a group of orthogonally oriented and interdigitated muscles without skeletal support. Key characteristics of the tongue as a muscular hydrostat include that the tongue’s volume is constant, and any decrease in one dimension will be compensated by an increase in another dimension. This work aims to identify causal relationships among internal muscles in protrusive muscle contractions, which is vital to understand their underlying muscle coordination patterns.

Abstract:
To safely land after a jump or hop, muscles must be actively stretched to dissipate mechanical energy. Muscles that dissipate energy can be damaged if stretched to long lengths. The likelihood of damage may be mitigated by the nervous system, if anticipatory activation of muscles prior to impact alters the muscle's operating length. Anticipatory motor recruitment is well established in landing studies and motor patterns have been shown to be modulated based on the perceived magnitude of the impact. In this study, we examine whether motor recruitment in anticipation of landing can serve a prote

In this thesis we try to model the spatial pattern formed by slow oxidative (SO) fibres in pig muscle. Unlike the other mammals, the muscle fibre pattern in porcine muscle is characterised by cluster of SO fibres dispersed throughout the tissue. The biological interests of modelling such a configuration are, on one hand, its peculiarity, and, on the other hand, the effective contribution of such fibre patterns to the quality of pork meat. Transverse sections of muscle samples are stained to enable discrimination of the fibres of interest. The distribution of the SO clusters is investigated in

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide. Besides abnormities within the respiratory system COPD is also associated with effects outside the lungs, so called systemic effects. One systemic effect that has been highlighted is skeletal muscle dysfunction which has also been associated with reduced exercise capacity. Apart from changes in muscle morphology, low levels of physical activity have also been suggested as a plausible mediator of reduced exercise capacity in COPD.

Prolonged computer work is associated with high rates of neck and shoulder pain symptoms, and as computers have become increasingly more common, it is becoming critical that we develop sustainable interventions targeting this issue. Static muscle contractions for prolonged periods often occur in the neck/shoulder during computer work and may underlie muscle pain development in spite of rather low relative muscle load levels. Causal mechanisms may include a stereotypical recruitment of low threshold motor units (activating type I muscle fibers), characterized by a lack of temporal as well as sp

Two different approaches have historically been taken to predict muscle forces. The first relies on electromyography (EMG), while the second attempts to predict muscle responses using mathematical models. Three such predictive models are compared here. The models are Sum of Cubed Intensities, Artificial Neural Networks, and Distributed Moment Histogram. These three models were adapted to run using recently

In this paper, we tested if this notion holds true for motor tasks that involve physical interaction.

Abstract:
The ability to control individual muscle activity is widely applicable in clinical diagnostics, training, and rehabilitation. Inducing muscle patterns that amplify abnormal muscle coordination can assist with early diagnosis of neuromuscular disorders. Individual muscle control also allows for targeted exercise of muscles weakened by disease, injury, or disuse. The goals of this research are to test a system for individual muscle control and introduce the use of muscle ultrasound as an alternative to electromyography (EMG). The system integrates a computational model of the right upper extremi

Abstract:
Abstract A model for predicting trunk muscle coactivation patterns is developed in this research. Electromyographic (EMG) data from ten trunk muscles were collected from 28 subjects as they performed simulated lifting tasks. Nine repetitions of each combination of independent variables were performed by each subject. Included in these exertions were asymmetric postures and dynamic (isokinetic and constant acceleration) exertions. The muscle activity data collected during these trials were used to develop marginal distributions of trunk muscle activity as well as a 10 × 10 correlation matrix th

Abstract:
The research on thermotolerance acquisition in broiler chickens by temperature conditioning early in life was focused on the following objectives: a. To determine the optimal timing and temperature for inducing the thermotolerance, conditioning processes and to define its duration during the first week of life in the broiler chick. b. To investigate the response of skeletal muscle tissue and the gastrointestinal tract to thermal conditioning. This objective was added during the research, to understand the mechanisms related to compensatory growth. c. To evaluate the effect of early thermo cond

Abstract:
The long term goal of this study was to reduce caloric and fat content of beef and other red meats by means of genetic modification of the animal such that fat would not be accumulated. This was attempted by introducing into the germ line myogenic regulatory genes that would convert fat tissue to skeletal muscle. We first determined the consequences of ectopic expression of the myogenic regulatory gene MyoD1. It was found that deregulation of MyoD1 did not result in ectopic skeletal muscle formation but rather led to embryonic lethalities, probably due to its role in the control of the cell cy

Abstract:
Invasive zebra mussels (Dreissena polymorpha) were first observed in situ at Apostle Islands National Lakeshore (APIS) in 2015. This report builds on 2018 SCUBA surveys and Environmental Protection Agency (EPA) veliger sampling to: 1) determine whether shoals on APIS borders act as sentinel sites to corroborate veliger drift hypotheses about invasion pathways, 2) evaluate ongoing hand-removal of zebra mussels from easily identified structures, and 3) continue efforts to assess native unionid mussel populations, particularly where zebra mussels are also present.

Abstract:
It is important to understand human kinematics and muscle activation patterns in emergency maneuvers for the design of safety systems and for the further development of human models. The objective of this study was to quantify kinematic behavior and muscle activation in simulated steering tests in several realistic conditions. In total 108 tests were performed with 10 volunteers undergoing purely lateral maneuvers at 5 m/s2 deceleration or simulated lane change maneuvers at 5 m/s2 peak acceleration and peak yaw velocity of 25 °/s. Test subjects were seated on a rigid seat and restrained by a 4
